Depending on how serious you are, I'd look into
http://www.taydaelectronics.com pretty early on.. I've built quite a few and kinda wished I had found tayda earlier. Their components are wayyy cheaper than anywhere else. Even if you want better components, enclosures and knobs and what not are much cheaper from there.
I unfortunately sold all my bits and bobs when I was planning on moving.. Have a couple pcbs I etched, I'll dig em up and let you know what I have if you're interested! ?
