Correct.

Not in my area.  I have one provider who is brave enough to ATM a t1 out
to my location.  Everybody else won't touch us.  Currently, we have what
our vendor is calling a burstable t1.  I don't know if this is a common
term or not, but bassically it means voice and data share the t1, voice
eating into the bandwidth as needed.  The t1 is actually terminated into
an Adtran 616 which I am currently researching to see if it can feed out
a t1 feed instead of the 10 copper lines.  But I digress.

Agreed.  However, given my options....

Well, except it's probably the best solution when you consider
cost/complexity.

Normally, I'd agree with you.  However, this situation is different
given the line costs.
