Gearbest has the CR-10 3D printer on sale for $339.99. This is $20 lower than it has been posted on SD recently. The CR-10 is a highly regarded printer with a large community of support. You can pretty easily find designs on Thingverse for upgrade parts that you can print yourself
Just add the printer to cart (make sure you select the US-plug version) and apply promocode 1111CR10
