Hi all! I am totally new to this but I am looking for a new hobby and this minibuggy idea has grabbed my attention. I have no fabrication experience, but I am mechanically inclined. I have put together a sandrail in the past. I say put together because I bought the chassis complete and built it from there. I have a Hobart Handler 140 that I bought a few months ago. So far all I have used it for is to build my welding cart (I'm impressed, but then I again I am easily impressed

).
Well I got bored of my jeep and sold it so I have about $2K to start playing with. I figure that will get me going and hopefully the money to complete it will come when it is needed. I have a ton to learn so I'm glad I found this site, but to start here are my questions:
If you were brand new to this and wanted to build your first buggy where would you spend your first $2K?
Do you need an engine to build around or do you buy plans that are specific to engines?
Thanks in advance for any information and for all that I am bound to learn from the boards!
