The best site for reviews is
LaxShopper.com - the Lacrosse Marketplace and this site.
For prices, I would check out:
The Lacrosse Equipment Superstore (overall good)
Welcome to TL Fritts Sporting Goods - Lacrosse Digest and North Shore Scuba Center (low price but killer shipping)
Jimalax Lacrosse Mesh (best mesh anywhere)
You should check out your local lax shop if you are actually buying gear. I buy from
The Lax Shack
