just this past weekend i got my bicycle stolen. nothing too expensive ($300) as i am novice rider but i am was riding everyday. anyway, i need some advice on buying a very good chain and lock. money is not too much of an issue here as the last lock, ($25) was obviously not a deterrent and i really don't want to go through this again. i live in nyc so the best i can get still might not even be enough but want to at least discourage theft. i have researched kryptonite and the nyc "fahgettaboudit" for about $100. is there anything better? should i buy a U-lock and a chain lock. i really love riding and want to feel use it as my primary means of transportation so whatever i have to do keep my bike i will do. thanks.
