3d Printers

Hello, I am not a sketcher but have seen some of the great designs on here. Also I know nothing about 3dprinting or printers and was looking for a few pointers.
I fancy getting a 3dprinter to mess around with, not for work or business, but just as a hobby. Can anyone give me an idea what I should be buying if I wanted to produce models that were about 30cm long.

Any tips greatly appreciated.

Thanks in advance

3D printing is nothing for people who don’t wanna fiddle around with the hardware as well as with the slicer software:
