FPGA - comparison of a few FPGA devices

• Open Workbench logic analyzer with the Spartan 3E 250E chip. -- $65
• Digilent Spartan 3E starter board with the Spartan 3E 500E chip -- $25
• Linsn RV901T board with Spartan 6 SC6SLX16 chip -- $20
• Pano G1 has the Spartan 3 XC3S1600E
• Pano G2 (I don't have) has Spartan 6 LX100 or LX150 devices.

• Digilent Zybo (and ebaz4204) with the Zynq-7010 -- $110
• Digilent Zedboard with the Zynq-7020 -- $220
• Ebaz4205 with Zynq-7010 -- $12 each (and I have 12 of these)
