I have a TM F-16 and F-22 for sale. Both have funky pots. I'm not sure if I have the keyboard cables, either, I'll double check when I get home. Otherwise these both have less than 10 hours of use and are like new.
Both sticks died really quickly, I then stuck them in the closet and forgot about them for a year or so. I've decided to get rid of them. My friend had good luck with the digital conversion on his F-22. If anyone here's interested le me know, otherwise they're going on EBAY.
