The $35 TI part is the TMS320C31, which comes in 33.3 MHz and 27 MHz versions.
The package is a 132 PQFP, versus a 181 CPGA for the 'C31.  PQFP=
plastic quad flat pack, CPGA = Ceramic Pin Grid Array.

The $35 is for the TMS320C31-27  which is the 27 Mhz version in the PQFP
package.  (in large quantities, as per the TI FYI  Vol. 7 issue 4 May 1990.

The 'C31 function are the same as the 'C30 except that it only has 1 32 bit 
databus, 1 serial port, and 1 timer.

I've been designing with the 'C30, and it certainly is an awesome chip.
Big iron in a small package.  Not only is it a great signal processor, but
it has a fine complement of general purpose computer instructions to 
allow it to perform system control.
