Thanks for the tip... figures I wouldn't try eBay for that. ;)
I was actually wanting one as an upgrade for my Coleco ADAM. I had installed a TIM board with the 9938 in one back in the day, and wrote some initialization software for it. Was thinking about building my own board to do the same again.

Hi! On the N8VEM project we are getting ready to release a
TMS9918/AY-3-8910 Sprite Color Graphic and Sound (SCGS) board. The board is
basically done and awaiting the PCB trace route optimization to complete
before ordering manufactured PCBs.
There are also plans for a follow on V9938 board. V9958 has "issues" that
make it less desirable than the V9938 IMO especially since it cannot
generate composite video. It can generate RGB video though and has some
enhanced scrolling ability. None of these chips can generate VGA compatible
video though so be fore warned.
As always, constructive comments welcome; send flames and pointless
criticisms to /dev/null
We've had some luck procuring the chips from leemoom611 on eBay. I've
bought several chips now (TMS9918, TMS99118, V9938, V9958) without issue.
Seems like a decent guy but I can't say much other than it worked for me. I
have no business connections with him other than a satisfied customer.
You are welcome to join us on the N8VEM project if you are interested in a
TMS9918 or V9938/V9958 home brew computer project or whatever you'd like to
do. Regardless, I wish you the best of luck with your project. Please keep
us (me?) posted on your progress.
Thanks and have a nice day!
