The TRX is an amazing tool. There was a rumor that there were some fakes being sold so just be careful if you don't buy from TRX. Either way, TRX came out with a new one late last year and it offers upgrades to their previous one that are, in my opinion, worth it. As for an anchor, you can use the door anchor, in which you just need a door to close and ample room on either side of the door to move - maybe 6 feet in either direction, plus about that, at least for going forward. It works a bit better if your anchor point is directly above. I use mine outside and used an eye hook. Works perfectly and while TRX sells an anchor if you want it, they recommend an eye hook if you talk to them directly. You will get an amazing workout using it, activating your core the entire time. Great for shoulder stability too. They have some great workouts but some are not real time, yet they are still good to learn and then do on your own. The workouts (unless you do downloads) come with a spiral book of the workout so you can follow without the DVD. Great for taking outdoors. I find that using this in place of weights is much kinder to my joints. It is fun and just as challenging, if not more so. The TRX is hitting all of the major sporting scenes. Todd Durkin's new book incorporates it quite a bit, and he also has some good DVDs out for TRX.
