ProTee camera alternatives

[Uva121]

Hi all, I recently purchased the base ProTee system from SwingSense (without the cameras). Could someone please recommend an inexpensive pair of cameras to add to the system? I saw PointGrey recommended in a few posts, but was hoping to avoid having to spend another ~$250 x 2. Would pretty much any "machine vision" camera work? I've seen lots of generic ones on Amazon or Ebay.

Unfortunately, I have to use the Pelz Floppy balls, as even the AlmostGolf balls are too loud in my apartment for my landlord/neighbors. Since I won't be able to obtain ~100% accurate readings w/ these balls anyway, I'm hoping a substitute for the Pointgreys may be possible...

Thanks, James

I think I have 2 extra PointGrey cameras. I need to double check, and test to make sure they are still in working order. PM me if you are interested.
