I want to get those bowflex adjustables.. but $400 on weights is not something I could swing right now.. I'll keep you posted over the next few months as to when I start again..lol
I've got a set of Powerblocks (powerblock.com), and they're great.
The BowFlex ones aren't as good as everyone says they are. If you accidentally bump them just right, all the weight discs just fall off (not good if you're holding them over your head!). That won't happen with the Powerblocks.
