I have dealt a lot with Fairfax Electronics in LA.
http://www.at-fairfax.com/ My man Shawn is the one you want to speak to. Good prices, and they are on the official vendor list. The only problem is they deal with a lot of different brands and product. So they are not 100% on support when you have technical questions; They have to ask them and take a day or so get response from Elk.
But their customer service is really good; had few minor hiccups with orders and they took care of it quick. Good people and honest.
