New to bike computers Looking for a bike computer that will work in conjunction with a trainer. Cadence, HR all that would be gravy on top of it but really I just want to know mile time and miles put on while I'm on a trainer, which is also new to me ;)

Friend says "just get a cateye" but of course there is about 30 of those and I've heard plenty of people say it's really hard to get a wireless one to work when mounted on a rear wheel.
