+1 on brothers, have used both brother laser and inkjets for years, and also the QL-550 ptouch I use for shipping.
I always have 2 lasers hooked up at a time, my "good" HL5340D which actually gets treated to proper toners etc, and a secondary one which I use for run-of-the-mill stuff, currently an HL2140 but 'm a cheap bugger, when toner runs out on the secondary, I buy another used brother with some more. Just bought another today for the princely sum of a buck fiddy to add to the stockpile, an HL2130.
Linux support is pretty good also for all the brother stuff.
