I want to try out 3D printing.
I've seen on ebay for ?88.99 (in UK).
Are these any good?
I read in other places these need a few hours to build.

Is there a newbie buyers guide somewhere?

I can't find on Amazon - assuming because of terrible reviews?
Should I invest a little more and buy something with better reviews?

Ideally, I did want something within a box.
These seem to be smaller + cost more.

The reason for wanting a box is because of kids - I assume the bottom plate gets hot.

I've seen others with a digital screen attached for a small amount more.
Do I need?

Thanks.
