Just got done with my first ride on the Road Machine and I'm glad I picked it up. Putting it together was simple, although I switched around the order of one of the instructions to make it easier. (throw me a comment if you need help) Once I got the bike on there it was very stable. I was using it in my attic, which likes to amplify noise to the rest of the house, but from downstairs it's just a very slight droning noise, not annoying or excessive at all. From on the bike, just the slight swooshing noise, but again, nothing bad at all.
This is my first trainer, so I have nothing to base it on, but I'm glad I went with this over the Cycleops as I saved about $80 at REI when it was on sale. (right now it's even cheaper on here)
