Protein Powder Recommendation

Spanaval

I currently have Designer Whey Protein Powder (Chocolate), and I don't like how sweet it is, and the weird kind of aftertaste it leaves in my mouth. So, I'm looking for recommendations for something that is

1. Less sweet. I couldn't figure out what the sweetner in this thing is, but whatever it is, I don't like it. It's been 3 1/2 hours after I had it, and I can still taste it. I'd much rather have something with just regular sugar than an artificial sweetner, even if it ups the carbs a bit.

2. Not too pricey

3. Comes in small enough quantity that I won't be stuck with it forever.

I don't like plain vanilla or strawberry flavors, but all else are likely okay, and anything chocolate is better.
