FitBit (or similar device) recommendations?

I have Lenovo hw2 heading my way. I chose it because of price, reviews, and the heart rate monitor. Takes about a month to get time, but most things do here in new zealand.
I suspect fitbits are overpriced as they are trendy. Do your research, read reviews. There will be compromises with going cheaper, for the Lenovo it was the app is apparently clunky to use. But it hasn't arrived yet so I'm yet to find out!

I have the Charge 2 HR, and I highly recommend it for your situation.

-It has a pretty thorough display when it comes to your stats, but it doesn't do much more to be fiddled with. The bells and whistles mostly go through the app, whereas something like their Blaze model, or a Polar, or an Apple Watch all have pretty vibrant, distraction-prone displays.
-iphone connectivity, so you can get call and text alerts, but they only show caller name or text name and preview (I believe this can be turned off so it only shows the text name) so again, not too obtrusive. You can also shut these alerts off or turn them back on with the push of a button.
-multiple exercise formats, which are meant to track more accurately depending on what you're doing. I'm not sure how realistic this feature is for most things, but it does seem to make a difference when I set it for elliptical.
-since tracking is mainly based on heart rate, it seems to be more accurate than most bands I've used, including other FitBit products.
-while you may get some false positive, i don't think it would be enough to exaggerate beyond what you're actually burning at work. It's actually somewhat difficult to just shake your arm around and pick up steps. I've tried to do that while stuck in the car on road trips (just to hit the hourly goal of 250 steps) and it's tough! I think if it's going to be an issue, it's something you'll run into on any wristband device. But I find the belt clip, wearable stuff far less accurate and harder to wear. I've lost too many clip-ons to the streets to count on those ever again.
-it tracks a great range of data, such as sleep quality, active minutes, floors climbed, and more. I don't even fully utilize everything it offers, but it's really cool what it can do.
-I don't LOVE the community there like I do here, but it's got its charms. The main thing I like is that you can participate in "challenges" with other users. This has contributed so much to my motivation to be active.
-connectivity with MFP, which occasionally is reported to be a little buggy, but for the most part they work well together.
-decent price point for the standard color models (I have a limited edition lavender strap for no good reason, lol)

I've used several evolutions of FitBits, a Polar, a Huawei Android watch, and an Apple Watch. My brother has a Garmin, which has the fitness orientation of Polar/FitBit combined with the stylishness of real watches, like the Android/Apples go for. While those are also really cool, and I could see some of their models working for your specifications, they can get wayyyyy pricey. I think all around, Charge 2 is a good option.

For what you do for a living I WOULD be very wary of any arm based tracker. I had a jawbone until it broke. I loved it so much BUT, I am a massage therapist. So obviously, I cannot wear anything on my arms. I did through a few sessions though just as an experiment. A one hour treatment got me 1500 "steps" but when I tucked the thing into my sock or just counted my actual steps around(and around...) the table it is more like 100.

So, you could wear one and just ignore the steps it tracks while you are at work, you could not wear it at all at work and just remember to put on and take off when you clock in/out, or you could adjust your step goals for a workday(wear it for a while, see what it gives you for work steps on average, then add steps that you would complete during your evenings), though this would mess with calorie reccomendations so not the simplest thing I know.

Jawbone is finally stepping up and crediting me for the broken band. In my little bit of reading I think I have decided to replace it with the Fitbit Alta HR as it is simple, not too bulky and I will use it a lot outside of work.

I would recommend a Fitbit zip. It's in the $40-50 price range and clips on your clothes. It's very basic if you are just looking to log steps.
