I'd not regard the dsPIC as a useful DSP platform at all. At low end an 
ARM is more flexible and better supported and FPGA otherwise. Microchip 
have even claimed the 18Fxxxx is a DSP chip simply because it has an 8x8 
HW multiplier. The Microchip 32 series are I believe   MIPS  core. 

FPGA can be cheap too. The lower end FPGA are even being touted as cost 
effective as CPU. Xilinx now promoting ARM Cortex M1 softcore rather 
than its own soft cpu cores. For any kind of decent image processing you 
probabily want a Virtex 6  or similar higher end  FPGA.

Is the Spartan 3E FPGA about same price as a dsPIC?  I think it's under 
$10. Though the Digilent Spartan 3E Starter kit (a good into to DSP) 
cost me maybe about 120 euro? It has Coolrunner-II CPLD, DRAM, Analog in 
ADC, Analog out DAC, Flash Memory, ethernet physical  and also  USB  
interface to PC for programming (no JTAG adaptor needed). It has some 
kind of video capture accessory bus connection, and VGA + 2 x RS232 and 
2x16 LCD all driven direct by the Spartan 3E FPGA.
