Kareem,

Radio Shack used to carry the $100 DATAQ DI-151RS 2-channel AD that
connects to the serial port.  DATAQ has replaced this with a 4-channel
DI-154RS unit that costs $150; however they offer an education discount
that brings the price down to $100 again.  Their web site states:

Special Offer for Educational Facilities
We are currently offering the DI-154 at a special rate of 33% off for 
educational facilities!  If you purchase the DI-154 with a purchase order 
from an educational facility, you will receive this special price.  Call 
1-800-553-9006 to qualify and to purchase your DI-154!

I don't know if Radio Shack will carry the DI-154RS.

This is great because it takes the pressure off of finding an alternative
AD source.

The DI-151RS works with Alan Jones' AmaSeis software and I hope the
DI-154RS will also work.

Cheers,
John

PS
Thanks everyone for all of the tips on other AD options.  I'll keep them in 
mind.
