Does anybody use a Bowflex?

its....JOHN B

im asking because i plan on buying one next year, but on the web site they have a couple different models, one at 3g's, 2 in the 2500 range, and one in the 1500 range, and im willin to spend the 3 g's if its worth it, but i hate buying ? on the computer when i cant test it out, im wondering if the one that cost 1500 called the bowflex xtreme 2 will supply everything i need, or should i spend the extra dough on one of the more advanced ones?
