RFC re Willem EEPROM programmers

I'm looking at buying a Willem programmer to go with my Data I/O 29B. Mostly I'll be using it for reading existing ROMs and programming stuff bigger than the 29B can handle. I've been looking at willem.org, on eBay, and at a couple of non-eBay sources. The first most obvious problem is that none of the available variants exactly match the willem.org board revisions, and I haven't found any cross-reference information. I'm probably not going for the new "true-USB" board. Any system I'll run it with has parallel ports. So... 1) I know a few folks on the list have willem boards. What board version do you have, where did you get it (if you remember), and are there any major pros and cons? 2) Does anybody here have experience with Kee Electronics? http://www.keeelectronics.com/ I'd rather buy direct than off eBay, and they look like a good product line. 3) Yes, I know the software's Windows-only. If anybody knows of a sub-$100 programmer with OS X software, I'd be overjoyed to hear about it. Otherwise, BFD; I have to keep a Windows box for work anyhow. Any input is greatly appreciated. Zane, I'm still getting a 554 reject from citrine.aracnet.com Doc
