Analog digital converters


Can anyone point me in the right direction here. Was trying to find out information on A/D converters. Have a bunch of old concert tapes that I wish to convert over to digiatl format. Tried searching the forums and nothing looked good.

What is your budget and what level of quality are you going to be happy with?
I use an E-MU 1616M soundcard (List $500) that has pretty good A/D conversion for doing Hi-Rez needledrops. I like it, although it has way more features than I need. I think the 1212M may be a good bang for the back as well and is a lot less money.
behringer makes an inexpensive a/d d/a that I use to digitize records. There are other units by m-audio as well as digital recorders with line in and out connections. Look in sweetwater catalog or guitar center online.
I use an M-Audio Audiophile USB outboard sound "card" that I found on eBay and paid well under $100 for. However I would love to have an Apogee Rosetta 200 one day, for well over ten times the price. In between, my choice would be an Apogee Mini-Me with USB.
Wadia makes a pair of units:

Folks,

Thank you for the suggustions. I think that there are several good ideas here. As to the issue of quality these tapes are old Grateful Dead recordings that are more for history that anything. But in the furture I think that it would be good to be prepared with equiptment that will give a good quality digital recording.
I did see the Wadia but I have a hunch that that maybe out of my price range the Apogee equiptment may fit in but tight. I do like the fact that the one is both a A/D and D/A. makes for one piece of equiptment.
