No specific advice.
I'd also love a home spin bike. I don't like the feel of my bike on the trainer, and sometimes rollers just don't work for my desired workout.
Around me, there's a
wholesale place that buys used Spin bikes from fitness centers, reconditions them, and sells them (sometimes, they have brand new ones).
They have Lemond RevMasters, Schwinn, Star Tracs (which my gym uses)...their stock is constantly rotating.
When I'm ready, I'd look here for what they have at that time. More costly, perhaps, than a Performance one, but it would be one I know could handle a spin class environment, so it could handle me in my basement!
Maybe there's something like this around where you are??
