NOTE: Because of school, I can only ship Fridays, Saturdays, or Monday if I know about it during the weekend. Please keep that in mind. I have to move a few extra items so that I can't get started on some new projects, so these have to go.
1) Happ 3" Trackball - white trackball - $45 shipped or best offer
This trackball was used for 5 or 6 months on an old project. No discoloration on the ball itself. I just disassembled it and cleaned it all up, it's in very good shape. Rollers are good, and have no grooves in them. They roll free, but can probably use a bit of oil for the best performance. I will oil it myself before shipping if I can find where I put the damn oil. 
This doesn't have an encoder. It has green Happ PCB boards and the 6pin molex. You will need a mouse hack/optipac/optiwiz to interface this. I can throw in a few buttons if you need mouse buttons... I have a bunch of colors, just ask.
TRADED TO STOBE
2) Tekken 3 PCB with Marquee -
$70 + shippingThis was in a MK cab I bought a while back. It works perfectly and was used for a while on and off in my JAMMA machine. I have to pull this to be sure, but I believe it is a Rev. B board... I'll get the info in a bit and post it here. When I first got it a friend said he didn't think this version was in MAME, but I'd have to look into that.
I also have the Tekken 3 marquee for it. Its in very good shape except for some corner damage on 3 corners. Once installed, you can't see it.
I'm always open to trades too

Feel free to offer whatever, the worst I can say is no. A few things I can definitely use are:
- two Sega cocktail control panels
- Jpac
- Arcade VGA
- 2 Wico 4way leafswitch joysticks OR 2 Ms Pac Reunion 4ways
- replacement Wico leafswitches
