Hello. First off I just want to say that I love my GEEETech i3 pro b. I got mine in acrylic. Had my 3 minions help with the assembly and it has been an absolute worhorse since. Here is my build thread for that printer:

These printers were a little tricky getting together because they didn't come with instructions just an inventory sheet and all the software they needed was on the sd card that came with the printer from ebay. The correct assembly instructions for these printers can be had here:

So good has my GEEETech i3 been to me. I detailed the first bunch of things I made with it here:

And then I started upgrading it for better features like better resolution and wifi capabilities and a touchscreen and whatnot. Those modifications went down here:

I think you should pick an open source printer like the GEEETech you had that is easy to modify as you grow and don't be so quick to give up. Get as far as you can on your own. Identify specific problems you are having 1 at a time and search out help here or on another forum for help. And one by one resolve your problems until you have a decent printing machine. There is a reason that the prusa i3 printers were so popular and it wasn't because they were a bad design and didn't print good.
