In the name of trying to save about 20 bucks, I ordered my video card (5002) for my 503cmx from dealznet.com. Talk about a nightmare, after a week, still no tracking number, still no idea were my order is, if it is shipped or not - but, they sure as heck took my money quick.
So, if there is a "bad distributor" list somewere on these forums, add these guys to it.
(mods, not sure if this is allowed, please advise)
