Thanks for the replies.
The pin is magnetic from what I've read so far. I've seen videos of people doing all kinds of excercises with them ie, shoulder press, one arm rows, curls, side laterals. So I think they are save to use. (granted I've actually seen a set of pro dumbells come apart and the 2 1/2 pound end plate broke a guys nose when he was doing incline presses- It wasn't pretty). So saftey is more important than convienence here.
I've got another post talking about the other equipment I'm looking at.... A cage is #1 though.
I'm getting a cage, flat/incline bench, 2 - 300lb Oly sets, and probably the Power Block dumbells.
If I were to go with the standard hex (cheapest alternative) I still would end up spending $1500 for the same set plus it would take up 15 times as much room.
We are building a house which is like 20 miles from the nearest gym. I already drive 65 miles each way to work so I'm not looking forward to another 20 mile gym commute 5 days a week.
I'm turning the whole basement into a gym eventually. First the important stuff like rack, bench, weights. After I get over the initial cash outlay I would like to get some of the rubber flooring and mirrors. They a lat/low row machine and finally a 45degree leg press machine.
The other machines probably won't happen for a few years but it's good to have goals!
