JD Industrial Supply is another great place to go. They have a great selection of sets and can also special order singles and anything else that's not carried. I bought my set of WrightGrip metrics from them. Veteran owned too, which is nice.
If you don't see what you want on their website, give them a call. I believe they can get you anything that is in Wright's tool catalog. They are great folks to deal with.
There is a company local to me called Production Tool Supply. They sell Wright,Williams, Wiha and just about every industrial tool imaginable. They have branches all through the midwest I think. http://www.pts-tools.com/cgi/CGPTHOME
Epsteins is Awesome to deal with but for Real Bargains find Wright "Auctions" on Ebay.. Obviously your Keen on Wrights Quality, As Am I, but Fortunately for Us the Market is Soft.
It does seem like another country dont it? It is the wierdest thing eastsiders dont come the the west and vice versa. I remember a few years ago someone visiting from another city was asking where the "outerbelt" downtown bypass was. I said it is that giant fishy smelling body of water called Lake Erie. Your stuck in traffic man no way around it unless you drive through some pretty shady areas. Everyone reading this check these guys out they have a lotof stuff.
Well I do travel to Parma for Honey Hut! That's about it haha.
I live in Beachwood and work in Cuyahoga Heights, we have people who live as far as Youngstown!
