Yeah, building a Fano-type to the same spec from, say, Warmoth parts would take you a long way towards that price. Unless you did the finishing yourself, which could save a fair bit, but it's messy. And then you've got the "to relic or not to relic" question... so far I'm not brave enough to try. I think it was a pretty decent price, really!
How do you find the Jazzmaster body, Dave? Does it feel big compared to a Strat or Tele?
