I would personally recommend proper telco-grade hardware for anything like this. For FXS, a TE110P and a Carrier Access Access Bank I would be perfect, and reasonably priced on ebay. It's highly unlikely that you'll need any kind of echo cancellation on a length that short, and the ABI can drive long lines. You don't need to worry about disconnect supervision or anything on FXS ports, either, which is why you can get away with the older ABI and ABII instead of moving up to the Adit600. Adtran and Rhino make FXS channel banks as well, and Xorcom makes a USB "channel bank" as well, but I have not used any of these products. If you're running between buildings you may also need to worry about grounding and protection. I'd need to know more information to be able to tell you anything concrete, but yeah, for under $500 you can have yourself 24 ports of telco-grade FXS to play with. (channel banks and fax machines also get along great, if that is a concern.) -A.
