Actually we have a really cheapo Brother unit here in the office, and it *does* scan to a Mac. But it's a bit finicky. The software acts up and sometimes won't scan unless the computer is restarted. This was supposed to be fixed in one of the updates, but it seems it has not been.

I was eyeing a new low-end Canon laser unit for home, but the scanning on those definitely doesn't work on a Mac; not even sure the printing works. HP low-end laser can be tricky with Macs; the cheapest stuff doesn't have drivers.

Canon usually supports Macs, though, so maybe we'll see some Mac drivers for that eventually. The unit I'm thinking of is the MF3240 which functionally appears to be a good bet.
