I'm using a Voicetronix OpenLine4, and it works well under asterisk. 
Initially I had some echo problems, but Voicetronix support is excellent and 
solved them (I've just updated the wiki with the bal# values they gave me).

I can't compare it to the TDM400, not having used one, but you can use 
multiple Voicetronix OpenSwitch 6 and 12 cards in one system without the 
interrupt problem of the TDM400.
