Newbie after printer advice

Hi all,

Complete newbie to 3d printing and I have done a little research but can't find what suits my needs so i'm turning to some more experienced hands on here!

I'm looking for a relatively cheap one to start with, probably around the 300-500 bracket.

I would like to buy a complete unit (assembly out of the box is fine but I don't want to have to research and buy bits and pieces form everywhere and I know i'm better off building one I don't really have time) and if possible one that can be easily upgraded over time if possible.

In terms of software I use solidworks every day for work so something that I can use my solidworks files to print off is what I would like.

Any insight and suggestions would be greatly appreciated!!

Cheers!!
