I don't understand the need to spend so much on a laser when it'll be, as you put it, used not that much.
First, my bias.....I don't like Lexmark, never have, never will.
That out of the way, lately, like the last few years, have been using Samsung laser printers and couldn't be happier with them, esp. considering their prices. My main is a Samsung ML-2851ND....bought last year when Office Depot had put them on clearance for $50 or so. But while it's normally sold for around $165, it's still a great printer.....but still probably more than you need to spend.
I'd reconsider your price point and look lower. Laser printers are always on sale somewhere.......take Office Max's sale paper this week, which ends today. They have a couple of lasers for $99, both of which are more than capable for your needs, I'd wager.
The $99 sale lasers are an HP Laserjet P1006 and a Brother HL-5240. There's an HP Laserjet 1505n for $199 if you feel the need to spend. OM even has some multi-function lasers like the Brother MFC-7340 for $119, a Brother MFC-7440N for $149, and a Brother laser, the HL-2170W, with wireless capability for $109. Heck, I bought a Samsung ML-2510 for a friend at OM a month or so ago on sale for $49 and after setting it up for her, I was astonished how well and fast it printed, esp. considering its price. (It sells normally for $99.......Newegg has it for that.)
Speaking of Newegg, they are selling the aforementioned HP Laserjet P1006 for $79.99 with free shipping. I'd really look into that one.
I'd keep an eye out for sales on reasonably priced lasers.....even the cheapies print crisp, clear text. What you give up with them is blazing speed (and they're still fast, just not as fast as the expensive lasers) and drawer paper storage, which could be an issue or not.
