I'd recommend BS, it's pretty great. I use a model F-122 (actually larger than this keyboard) every day, and I love it.
I believe these keyboards work over normal PS2, but I haven't tried. you have to be careful: some will only work with terminals. There's a lot of weird stuff with these, but I think they just use terminal emulation software, and will act like a regular KB normally.
Ofcourse they might not. I wonder if someone has one already, and they can weigh in.
