Well my advice would be to learn using the one you have rather than jump straight into buying another. Lots of people have that printer and it works for them and 3d printing isn't something you can just do once you have a printer. You need to put a lot of time and effort into keeping them running unless you are in the > $30k market and can pay someone to keep it going for you.

Use the forum to solve the problems you have with that one, it will serve you a lot better in the long term.
