Ya I've seen the Bowflex ones, the only problem is that 55 lbs ain't going to cut it. I just found these
Ironmaster Adjustables that go up to 120 and more like a normal looking dumbell for alot less. Going to be check up on these ones also.
I get where your coming from Dr. X but I am looking at this from price/conveinance factor. Being that I will probably be moving alot into small apartments over the next few years I kind of planning ahead. Changing the weight really isn't an issue with them either as it takes like 5 secs on the stand.
