have you looked at...kreitler rollers for training
http://www.kreitler.com/accessories....pg=accessories
We (dh & I)have these alloy rollers with headfan and front fork stand. The fork stand is a must as far as beginner/Interm. are concerned-and wearing clipless pedals and shoes. We both really love them, they also have a great warrantee, and any extra parts can be bought seperately. I also like the fact that it is the front wheel I have to remove instead of removing/replacing back wheel. Find that if something is simple I don't mind moving bike on and off as much.
Look into them, there are a couple of other people here that use the rollers as well and seem very pleased too.
