I've been wanting to get one for a while. They are great. Friend of mine has one and he loves it.
I think the best one are going to be online.

my friend has the 40lbs one that shows the blocks of weights.
I was thinking of getting the X-vest. It is said to be more form fitting.
I've also seen the X-vest for $50 dollars cheaper so I wouldn't buy from these sites
