I'll second the printrbot play.
I use a printrbot play, and I'm very happy with it. $400 entry level printer, recommend a y-axis upgrade and a zebra-plate from printinz. I also use hatchbox filament from amazon.
You could realistically increase the Y axis with only two longer 8mm rods, a printinz plate of equivalent length, and a GT2 belt.

Nothing should be getting wet but it could be humid out while in use.
