I'm not sure, but I think your best price/performance solution
might be a very small linux system (1U or smaller) with one
Digium TDM400P+4*FXO daughtercards.  At least the the size
point of 4*FXO, this may turn out to be your winner.  If it
boots from flash, your cleaning lady can always apply power
cycle for anything you can't fix via ssh...  

By using this solution, you would also get the ongoing 
bandwidth benefit of being able to trunk all 4 FXO calls
out in a single IAX frame.  This will save you money on
an on-going basis if your bandwidth costs are significant.

Perhaps Soekris would be a good box for this solution,
but there may be even smaller devices with the needed
1*PCI interface, I don't know.
