Welder Purchase

Alright... i am fed up with looking for a trailer that will fit my needs! I am ready to build my own!
TSC 5x8 is L channel and cheap
HF is 4x8 cheap and C channel
Redtrailer.com 5x10 is boxed steel but $700 with shipping.
So now i am looking to purchase a welder read a few books and go to a training course on welding at the local vocational college.
I need recommendations on a good welder. I hate buying cheap tools that dont last. So i want a good welder in the $500 range (If that is possible).
Thanks All!
Also i need contacts for getting axles! The dexter seems to be the axle of choice?
