Budget DAC with switchable inputs

I've got a vintage Kenwood receiver with some KEF speakers and a Kyocera PL701 Turntable. Not an audiophile set-up, but I like the Kenwood tuner and slight warmth. The trouble is lack of inputs. I've got three or so things to plug in but only two inputs. And I want to add an Airport Express to stream Lossless audio to my stereo. I figure it'd be better to let a DAC handle that and use the optical out of the Airport Express. Then if I get a DAC I can send digital audio from my DirecTV box, low end DVD player, and from my pro High Def video card that's in my Mac tower. I'd love to find one for well under a thousand that can handle at least two optical inputs and one coax. I've been searching these forums and other places and haven't found anything that fits these needs.

Baring that, maybe there's one that can switch between one optical and one coax input. By coax, I mean the digital connection that uses RCA connectors (is that the right terminology?).

Any suggestions are appreciated!
