For those of you that are not interested in paying $200 for TRX, I did some research yesterday and found some alternatives for you... which are listed below.

1) GoFitGravity Strap
2)Seirus Strap Suspension... has lots of videos
3) SKLS Power Straps 90 day warranty
4)Lifeline USAJungle Gym USA made and 90 day warranty, these are built for commercail use.

After looking at all of the straps etc... it does appear that TRX is the best quality and does have the best warranty which is one year. But prices range from $49-$99, so that decision is up to you. There may be even more choices than what I have listed.

Ok, hope this helps...
