PS2 Wireless

I was at circuit city today trying to decide which ps2 wireless controller to buy for my lynx5 arm and my hexapod. I got frustrated; I wasn’t sure which one to buy.
They had Mad Catz® MicroCon Wireless Controller $19.99
and Pelican AfterGlo Pro Controller $14.99 and…

Do you have any recommendation which controller I should buy (with a good range)?
Thank you

Not sure about the range, but I suspect that they’re all similar.

As for which to get, go with the MadCatz.
Jims says in his tutorial that he’s tested them and they all work great.
