Monochrome laser printer recommendations wanted

[Tecolote]

Looking for a B&W laser printer, and have some fairly specific requirements to meet:

1. Budget~Don't want to go much over $220, and prefer spending less.
2. Auto-duplex~Definitely do not want to fool with doing manual double-sided printing.
3. Resolution~Printer has to be able to do legible fine print, and good quality photos.
4. OS~Printer must handle both Windows XP Pro and Linux.

So with those requirements ever in mind, I have done a lot of research and believe these models to fit the bill:

Brother HL-L2340DW
Brother HL-5200DW
Brother HL-L6200DW
Canon ImageCLASS LBP151DW
Canon ImageCLASS LBP251DW
Canon ImageCLASS LBP6230DW
Samsung Xpress SL-M2825DW
Lexmark MS317dn
Lexmark MS417dn

Any help to cull the herd would be appreciated. I need to whack these down to the pick of the litter...say the best three choices.

I bought a Dell 2330DN with the toner and drum on eBay for £30 (including postage!). So far it's been great: it has a resolution of 1200dpi, auto-duplex, networking and dual paper inputs. Only criticism is the inital page curl after the paper emerges from the printer, and the first printer I was sent had a slipped gear. If you're in the UK, I got it from this seller on eBay.

Thanks, I will keep trying to find one. So far the only Dell 2330DN available in US is refurbished, which I avoid. Also, I managed to whittle down the list to just two:
Brother HL-L6200DW
Canon ImageCLASS LBP251DW
Any opinions on these?

After a lot of procrastination I decided to buy the Brother HL-L6200DW...due to arrive in a week or two. Thanks to all for the advice!
