I've checked with CompUSA both in Houston and Denver. They do list the 3800 PRO version for "deliver to store" pickup. So, if you want to pay several hundred dollars extra for the RIP, then CompUSA could be an option. Their staff wouldn't speculate if the standard 3800 would ever be offered.
I also wanted to deal with CompUSA because their warranties are usually reasonable and I like the idea of carrying in the printer, rather than dealing with shipping these monsters.
