Hmm...moi?
With lasers, you can almost buy on price. There are a few that are pains, but in general you can usually find one so cheap you can throw it out when the toner cartridge runs dry.
Color ones have gotten pretty dang cheap by the way...
Scanners...different matter...do you need sheet fed or flatbed? If you're doing books and magazines, you'll want flatbed. If you're feeding 20 sheets at a time, sheet fed. Both are available on some models. Are you just scanning images or do you want to try to do OCR (optical character recognition)? If images, are they particularly high res or just stuff ya wanna pull in and stick in a document?
I'd suggest avoiding the "all in one" models. One thing breaks, the whole thing is worthless.
You can get some occasional sweet deals at the office supply stores (staples, etc)...look at costco/sams as well...some of their printers come with FULL toner or ink cartridges instead of the 'starter' ones.
