I see that there's a Panasonic KX-P7105 on pricewatch right now for $299.
It looks like a good printer and I think I'm going to get one. I'm looking for reviews right now.
It does 15ppm, 1200x600 dpi, auto duplex, has 16megs expandable to 48megs, paper cartridge adjusts to all shapes and sizes, 4000p at 5%, and is usb/parallel. If you want ethernet, then I would look at the KX-P7110, which is basically the same as the 7105, but looks like it has ethenet too but it costs over $100 more.
If it is as good as it looks, it will be a wicked deal.
