I recently bought a new
Xeltek SuperPro-610P on
AliExpress for $268 shipped. It works great. It's USB connected and has its own external regulated supply. It also supports ISCP using a DIP adapter (you can buy one or just make your own).
Wrt this thread, it supports TMS2532, and many PAL/PALCE/GAL devices. I've used it on Lattice GAL16V8 and Atmel ATF16V8 with no problems.

610p.
The 610P programmer also has 4000/7400 logic chip test support and the ability to allow you to create your own custom logic tests. If someone was ambitious, they could probably create a test sequence for the Atari AVG chip if they really put their mind to it.
I used to use a Xeltek SuperPro-Z with a parallel port. I wanted something that would run natively under Win7 and from USB and that was supported by free updates. I bought a MCU Mall GX-4Q and it works on older EPROMs using an external supply. However, it doesn't test logic and I wanted to have an alternative device on hand so I bought the Xeltek SuperPro-610p as well. I have not been disappointed.
The price for the Xeltek SuperPro-610p at most Canadian distributors is ridiculous at around $740 CAD and I've seen it priced in the USA starting at $400 and as high as $650. The unit that I bought at AliExpress is the exact same device and it came with the OEM compartmented box, supply, CD, USB cable. I recommend avoiding listings offering the 610P with a bunch of cheap package adapters because those adapters are generic, not specifically for the 610P and they are available very cheap separately.
