My suggestion is by a kit you can afford and assemble a kit .
Tin
for a kit of comparable size (actually, it has a larger build area) take a look at the Folgertech FT-5.

It comes with everything needed to build a working printer, and the price is very attractive for the size.
The downside is that the documentation is not the greatest.
The upside is, I have built one and it works pretty well - I can probably walk you through any issues you may come across.
Tin is right in asking if you have the Knowledge, Skills and Abilities to attempt something of this nature - even in kit form. And let's not forget about the tools required - a good soldering iron, a decent multi-meter, and various hand tools, and the ability to use them, are all required to build a printer.
not trying to discourage you from this - just want you to be realistic about it.
