guys - Just bought a Trek FX2 for $500 and wanted to know what's the best bike lock. I'll be riding it in Manhattan mostly during the day - won't be leaving it overnight anywhere since it'll be parked in my garage. I don't want to go crazy but hoping to find a lock which offers best value and safety. Is the best way still to use two locks - one to lock front wheel to frame and another to lock rear wheel to a pole? Also, is U-lock enough or you've been in situations where you need the length of the cable?

About safety, I've also sort of believed that if you try to over-protect your bike with real thick locks like this one (Kryptonite New York Fahgettaboudit Mini), then a potential thief may see your bike as being very expensive when it's not!

Thanks
