My opinion only...
Complete is the way to go on a budget.
Custom is the `old school' way, like back in the day, but with decent parts now!
Take your time, there is so much good stuff about, 1 or 2 years old, kids learning to drive, need insurance money... = bargains
The only problem for me is knowing what is `in' and what is `sh!t'. Most of it looks the same!!
But rest assured, whatever you choose, whether it is good, bad or indifferent, you will get support, or pi$$ take from your brothers on RAD. (and none of it matters in the grown up world!)
The best point of it is, you are still happy to invest in this crazy world/sport/art of ours, and long may it continue.
Looking forward to seeing what you get.
