[sdiy] Universal (EPROM) Programmer - Redux

[MTG]

Well we had this conversation in August 2010 and at that time I bought a 
Galep-5. It really supports a lot of devices ("more than 62,000"), but 
now has serious USB connection issues. And judging from the forum it's a 
pretty common problem. I've reflashed the thing, updated the software, 
etc... no improvement.

So now I'm looking again at what I can find in the approx $500 price 
range. The Galep-5 is really slow to boot as it has internal Linux. I'm 
not sure why that would be a feature but they seem to think so.  I would 
like to be able to program old (small) devices needing at least 21v (25v 
would be bonus) such as say 2716. And I also use it for larger/newer 
things like 27C400 40-pin guys.  MUST BE USB and support new Windows 
OS's such as Win8 x64.

I need recommendations please!

Here are a couple I've been checking out online:
