P90X and HRM

Hey, I'm going to be getting the p90x dvd and pdfs etc. and I'm just wondering what sort of equipment is needed for it? At home, I have a elliptical trainer and weights - Will I need to purchase other equipment? I'm very heavy so a pull up bar would probably fall down lol!! But yeah, any help and advice would be lovely !

Also, for those in the united kingdom - What HRM's do you have? I was thinking of purchasing this one; http://www.ebay.co.uk/itm/POLAR-FT1-WRISTWATCH-HEARTMONITOR-TRAINING-COMPUTER-/120780710993?pt=UK_Sporting_Goods_Activity_Monitoring_MJ&hash=item1c1f176451#ht_784wt_1396

As at the moment, money is a little tight due to me getting laid off from work and I've got a hell of a lot of time on my hands at the moment as I'm caring for an ill family member so I get most days free so I've decided I'm going to dedicate it to my exercise.

Thank you
Dan!

P.S. Add me to friends, I'm looking for some more peeps!
