In addition to a few threads on the subject here, there's also a
good one over at the EAB.
I bought a working Willem and 16-bit adapter from
KEE Electronics. Whatever you do, _do not_ purchase the adapter from Sivava. Their programmer works fine, but the adapter caused me unending headache until I finally discovered it was defective.
IMHO, the best reason to do this is so you can modify the ROM contents. The BB2 upgrades,
these patches (second one down), exec441 and various BlizKick patches (from the most excellent Piru) are some of the usual upgrades.
This makes the most sense on accelerators without maprom space. (Of course, it's handy to have for burning unmodified ROMs, too.) Otherwise BlizKick and RemApollo work well, if you have supported hardware. Personally, I like to burn a ROM regardless to avoid a reboot.
