I've done business with Del-Ton in the past, long before the 2008 election and all the nonsense that followed. They're based in Elizabeth City, NC, and used to come and set up at the Raleigh gun shows. Very nice folks. Since 2008, they haven't come to the shows, but I still deal with them via online and phone orders.
Anyway, when the craziness started following the 2008 election causing a shortage in AR's, they extended their delivery times but NEVER raised their prices. Some orders took many months to fulfill, but were honored at "pre-hysteria" prices. That says a lot about the company, as far as I'm concerned.
Recently I received an email promotion from them offering a complete M4 rifle kit (except stripped lower, and no rear sight) for $450. I waited too long (1/2 day) and missed that deal, but the point is that their pricing has stayed quite reasonable. Of course, like most AR vendors these days, they don't have much in stock, so you have to watch and be ready to order when stuff is available.
I had one problem minor problem with an upper and they turned it around and shipped it back to me within several days. That's the fastest turnaround I ever had from a gun company, plus I got a call from a knowledgeable human being about the problem when they were looking at it.
If you haven't gotten the idea yet, I like dealing with Del-Ton!
