I got the Tactical Training Laser Cartridge from Amazon for $50, printed my own target and use a free program called Sharp Spotter. I happened to have a webcam laying around, but it'd only costs about $10 from Amazon anyway.
It's been working great so far. The only downsides are:
- The target can't be very well lit, and
- every time you move the target or the webcam, you'll have to adjust the mapping; if you are not too picky, it only takes a few seconds.
