I would recommend the OV2710 usb cameras from eBay that will do 100fps at 640x480 (does not do 120fps as advertised).
If you are looking to do a 2 camera setup, skip the ps3eye cameras.
while you can get it to work, it is not easy to do. i've had a couple of people contact me after purchasing two ps3eyes cameras, asking how to get them working with the dual recording script. Primarily I don't want anyone to think I am using ps3eye cameras for a dual recording setup.
I figured I should start a new topic because the other thread has gotten a little long and confusing.
