This time of year there should be some good LBS closeout. For your first set of kit it might be a good idea to be able to get your hands on it in person - - for example to figure out whether you must go for the ignominy of 'club cut.'

From there you can measure your good-fitting kit to compare to online charts better.

Failing that, Bonktown and PBK, probably. Check the coupon codes forum for your 5, 10, or 15% off at PBK...
