When I had a PC I was a die hard Edge 2000 pad user. At one point, I had a really bad experience with LC and swore off their products.
So, when I switched to the Flex I emailed Aaron at Edge to see if he was considering making an adapter for this machine. After a little research, he told me that it would be some time before he could come up with an adapter for this machine if it could be done at all. So, I begrudgingly sold many of my Edge pads and bought LC ones to replace them. Well, it seems development has been more speedy than Aaron initially said. Lay your eyes on this:

I'm told there's still much more testing to be done, but the adapter may be released next month.
