Hey all, saw the (old) video on the $50 universal programmer, it looks pretty great, and they are right around that price:

I do have a couple EPROMS, but not many other chips, the stuff that would be more interesting is being able to read/write modern i2c eeprom chips, I'm doubting these can do it, if they can great, if not, I am wondering that can? A similar program interface where you could read/write, see the data and save it to a file would be awesome.

i2c chips are very easy to read and write. Pretty much any decent PIC chips has i2c functionality built in, it would take maybe 20 minutes to write a program to read the eeprom and send it to pc through serial.
Arduino also has i2c and I think there's even some ready made example program in the Arduino ide to read or write a byte to i2c eeprom.

It supports the CAT24C32, only one I've tested.

Check the support list for specific devices.

I2C EEPROMs are pretty standard, there are a ton of 24Cxx devices in that support list, they'll all be basically the same protocol.

Buy a Bus Pirate, and it will do pretty much any I2C memory out there.
