Haven't seen an affordable Cadillac, but have been using the sangoma 
A200D with no problems whatsoever for about four months.

I've got a TDM2400 here to be tested (since we have somewhat unusual 
pstn lines), but haven't had time to install it as yet. We've also had 
the TDM04B in use for about two years, but still have less then ideal 
voice quality due to small amounts of echo at random times.

I too have gone through the spa3k, 488, mediatrix 1204, and others but 
have not found the Cadillac as yet. The mediatrix produced the best 
audio quality, but at the time I tested it, it had lots of other less 
then desirable "features". Some of those "features" have since been 
corrected based on what others have said.

As of right now, I'd consider the A200D as the closest to being a 
Cadillac since its h/w ec works very well (on our pstn lines), and it 
supports analog modems (fax machine) "if" the A200D has both an fxo and 
fxs module on it.
