Laser for Ubuntu w/Duplexing

[yester64]

Hi, do you have any recommendation for a laser with a duplexing feature? The duplexing is a must, so i might be a little limited.
I check some out, but Lexmark seems a little high for replacing cartridges.
But i am not certain really which brand is better to work with linux. So i relay on you guys.
I have an older Brother but needs a new toner and drum. So i just replace the printer.

Thanks

At my office we have an HP LaserJet P3005 hooked up to the network and it works perfectly. Don't know if that model is still at sale though, but probably there's something from the same series available.
