For my FPGA-Kit decision of LX9 MicroBoard, Nexys 3 or Atlys I have 
created a comparison list, which is attached.

Here are my personally pro and cons:

LX9 from Avnet:
+ small and low price (103€)
+ good user guide and video from Avnet for beginners
+ all SW-licenses for LX9 included (Chipscope Pro and SDK)
+ for PMOD-Interface there are available a lot of modules

- only 16 I/O available externally from two PMODs (12pins)
(PmodCLP (LCD parallel) uses already nearly both PMODs)

+ 72 I/O available externally from 4 PMOD and 1 VMOD
+ power supply from USB or external wall-power supply
+ USB Host for mouse, keyboard and USB-Stick
+ VGA Interface

- no SW-Licenses included (price on Xilinx is over 3000€)

+ high performance
+ HDMI Interface (2 In and 2 Out)
+ AC-97 Audio Codex

- for power supply always external wall-power supply necessary
- no SW-Licenses included
- expensive (319€)
- only one PMOD interface

Because I would like to take the kits also on business trips with me and 
I do not need HDMI yet, Nexys would be my favorite, because of the high 
number of external I/Os.

On the other hand, with the LX9 I get the normally expensive SW-Licenses 
and it has a better user-guide for beginners.
