If you can afford one, the Ultimaker 3 is fantastic and extremely easy to use! I've been using one for two weeks. It was pre-built and after unboxing I began a complex print with water-soluble PVA support material in about 20 minutes.

Ultimaker is a supporter of open source hardware: https://ultimaker.com/en/blog/17799-releasing-our-source-fil...

If I were replacing my Prusa with something off-the-shelf, I'd buy Ultimaker. My previous maker space had four of them, and they ran those things constantly with minimal fuss.

They are a bit pricey, but there's the option of buying used - lots of people buy 3d printers, and then realize they don't use 'em and so sell them second hand.

Let me first apologise for the late response. I am sorry I had forgotten about this thread.

The best 3D printer IMO is the Original Prusa sold by Josef Prusa himself. shop.prusa3d.com

3D Hubs also has a great section on 3D Printer reviews and ratings.

Flashforge, about 700 to 800 on Amazon. qidi clone is 400. Monoprice.com has a basic one for 349. Parts cost about 200 if you diy, I am told.
