I use the TDM40B cards, but I'm in .nl - I've had no issues at all the
TDM40B supports 4 modules which can be a mix of either FXS or FXO...
Currently I'm using 2 of them 1 providing 4 FXS and the other 2 FXO. 2 fxo
ports have 2 separate DECT base stations plugged in and there's no issue
with that either.

If you use the SPA-3000 you'll only need 1 since it has both and FXS (what
you plug a phone into) and an FXO (what you plug the phone line into) port

Personally I'd stear clear of the X100P (single port fxo) and don't even
think about one of the clone cards. Your other option is a VoiceTronix
card, but I suspect that it's a little too expensive if you are just
playing.
