I recommend "Brother HL2140" If you have more budget, get Brother HL2170W
Brother 2170W has wireless supported
I have Macbook Pro C2D 2.16, iMac 3.06Ghz, and another Macbook Air.
Both machine work very good in office and at home.
I have 2140 in the office and worked for about a year without problem. The 2170W is currently at home and working fine.
Good lucks~
I used to have HP LaserJet. HP is a good brand with fair quality. I replaced all of them because the roller issue. It easy to get paper jam and cause fuse burned issue. An fuse cost me about 75US dollars.
