DTV box question

[Garrard201]

I got my DTV coupons the other day, and tried to buy a converter this weekend for my old Sony TV950. However, I cannot find anyone selling the models that will pass through LP TV analog signals. I work for a company that owns several LP's, so I want to be able to watch them, too, and check on things. I don't have the model #'s in front of me, but there's one Magnavox, 2 Philcos and one other that do this. Best Buy, Circuit City, Radio Shack, K-Mart and Wal-Mart only have 1-2 models each (and none of those will pass analog). What to do! I even tried the vendor links on the FCC page.
