Over the past three years, I've used the x100p, tdm04b, and the a200d. 
I've got a tdm2400 here (on loan), however due to personal issues 
(cancer) I'll need to return it without doing a formal comparison.

My inclination would be to go with the a200d as sangoma seems to fix 
issues rather quickly. If you check the archives for the tdm2400, you'll 
see where fixing issues with it have drug out over months and I'm not 
sure if all the known issues have truly been addressed as yet.

In addition, the tdm2400 card uses the large centronix-looking 
connector, so you'll need to purchase a patchpanel (or whatever) to 
break those 24 ports out into something usable.

The a200d has been in use here for about six months and has provided 
rock solid performance over that time. I've not even bothered to upgrade 
the drivers for it.  I'm using both the fxs and fxo modules, and do send 
fax calls via the card.
