I like R & L Electronics. Never had a problem with them that wasn't instantly rectified. If you want to save a little dough, R & L Electronics and Gigaparts sell cheaper than HRO and DX Engineering. Yes, I know about all the price-matching stuff, but R & L and Gigaparts have lower posted prices on their websites. I don't play the price-matching game.
I just wish R & L still put out a paper catalog. It is a heckuva lot easier to shop a paper catalog then order via the Internet, than spend time trying to find things on some of these websites. All websites are not created equal!
