I do 100% of my training rides indoors. I have a crazy cheap trainer which I spent $600 3-4 years ago (really could have gone much cheaper off of CL's or something) and its not left the trainer since. The bike is set up to the same measurements as my race bike (Dimond) which cannot be ridden on a standard 'fixed' trainer. If you really want the QR (ie it fits, you think its rad and you'll race it hard) then get it, and just set up a dummy training bike.
Side note, something like the feedback sports Omnium trainer or typical rollers could be an option as it doesn't fix the rear wheel.
