[Coco] Cheap alternative to the DE-1?

That link was a monster! Here is a shorter one that takes you to the same item:

I ran across this while surfing E-Pray this morning. It looks
   interesting.
For those, like me, who are interested in FPGA's, this
   $70.00 unit seems to
have everything needed to port Gary Beckers
   CoCoFPGA to it:

-Learning-Board-EP2C8Q208C8N-LCD1602/272020523309?_trksid=p2054897.c100

k%3D12%26rkt%3D21%26sd%3D261661704545

   It uses a smaller FPGA so there may be
a limit here. I'm not sure how
   many LE's Gary's code uses.

   This board:
EP2C8      8,256 LE's
   DE-1: EP2C20           18,752 LE's

   Also, there are
only 2 PLL's and I'm not sure if both are connected to
   clocks. I bought a
small FPGA that had 4 clock inputs with 2 PLL's. The
   moron who designed the
board connected the clock to one of the CLK pins
   not connected to the
PLL's.

   This board:     2 PLL's This assumes there are clocks connected to
  
both.
   DE-1:              4 PLL's DE-1 uses only 3 (one connected to the
  
external clock)

   Since Gary posted an "almost" up to date project of his 3.0
FPGA code,
   i went ahead and bought one to see if I can port it. It comes
from
   China, so it wont arrive for a while (slow boat from china joke in real

life). I'll keep everyone posted.
