Analog to Digital converter recommendation

I currently own a Camelot Uther D/A converter which also functions as my preamp. I have been very satisfied with the sound of the unit but I wish to connect an analog tuner. The Uther only has digital inputs. Can anyone make a recommendation for a decent but inexpensive analog to digital converter, hopefully in the $100-$300 range, which will accept stereo RCA's from a tuner or other analog source and output to digital with sample rate of 44.1 kHz? Sound quality is important but in this case I will be listening mostly to talk/news or background classical music.

In that case I would go to radio shack and buy the one they have for $40. try it out and if the sonics aren't good enough, just return it and get a refund.
The ubiquitous ART DI/O would work for this, but you'd need a pair of RCA to 1/4" phone plug adapters. Digital output is coax (RCA). You can select sampling rates of 44.1, 48, 88.2 or 96 KHz.
Thanks for the responses. I ended up taking your advice Cadet1 and went to Radio Shack. 40 bucks later I am now able to listen to my Adcom tuner through my digital pre. Thanks much for the advice. I tried Radio Shack once before but when I described what I was looking for they looked at me like I was crazy. Oh, and by the way the sound is quite good considering the analog signal is being converted to digital then back to analog. I'm keeping it.
Some further followup for those that may find this thread later... I bought a Ratshack A2D--I needed to convert the analog out of my CATV box to digital coax, since my system has only PCM digital in (and the CATV digital out is Dolby). The Ratshack has some low level threshold circuit that cuts off the A2D conversion when the signal drops and also makes a "thwip" as the A2D cuts in. What that means is that you get a disturbing series of odd heartbeat like noises during low level passages. I've got an ART DIO on order. For those that come afterwards, skip the RatShack.
Radio Shack must have come to the same conclusion as Edesilva, since they apparently have discontinued production of their A2D converter. The good news is that existing store inventory has been marked down for clearance. This $40 unit is now being sold as a discontinued item for $3.74, not much more than a Big Mac. I couldn't resist, so I bought one today. Get'em while they last.
