I love my CR-10 and would totally recommend it. I made a lot of videos on my youtube channel about it here: www.youtube.com/3dnow The CR-10 has been one of the best selling 3d printers for a while now for plenty of reasons; Low price, huge heated bed, many materials, fast printing, great build quality, easy to use, etc.
I have a coupon to get the CR-10 on Gearbest for $339.99, which is by far the lowest price I can find.
The coupon code is: 11CR10US
With the extra money, you can save it or buy a lot of filament! Dual extruders is cool, but a little hard for beginners and on printers under $450.
Let me know if you have any questions!!
