I sell HP's at staples (which isnt' the best reason to trust my opinion -- most salesmen i've met are full of shit, so the credibility is not there)... but the biggest reason to trust my opinion is becuase my mom used to own a business doing graphic design, word processing, etc. and I would pretty much maintain the machines she purchased. The office equipment she had the best luck with is definitely Hewlett packard.
Do NOT buy a lexmark!! Lexmark black inkjet cartridges cost 30 - 40 bucks.. and get about 250 pages printed.
HP black cartrdiges cost $20, and get about 400 pages.
Epson cost about the same per page -- but Epson's cartridges are just ink tanks. The print head is built into the printer which is one thing these reviewers nevre take into consideration. When the print heads (nozzles) get dirty or old, they stop working. They typically go bad after about a year and a half, and the repairs cost more than $150.
You said laserjet? I like laserjet's too - and personally own a Laserjet 3, and a laserjet 4 plus. These are both office-quality machines and cost >$800 back in the day. We still use the 7 year old laserjet 4, and it prints just as clear as the newer ones and never gives up.
I like the HP 3380. It is more expensive, but uses a higher yield cartridge which saves money in the long run. Any HP will work absolutely great.
BTW don't tell staples, but those extended warranties are bullshit -- don't waste your TIME or money
