for dirt cheap,, check out the HP4600 series. You can get one for few hundred in decent shape. Toner is cheap as the printer has been out for 10+ years. It does take a little to get going (it calibrates when it's woken up), but for that money it's hard to beat. There is an issue with early, early versions. If you are getting one, it has to be a version 2B or higher (or something like it, PM me if you really need the info).
If not the super cheap route, look into off lease high volume office multifunction machines. $15k units sell for $1k and up. They are rated 100k pages for month and last pretty long time. They offer mailboxes, fax, scan, document memory (you can save your forms and print as needed from the printer, no computer needed) and so on. Print color in 30-40 pgs/min with only a few second delay. We tested the Toshiba E Studio and it was really nice, just not worth the $15k price they were asking for it. We'll pick up a used one probably later this year.
