To save a few more bucks, you could do what I did; wait until Guitar Center (or some other retailer, if you like) has a 10% to 15% off e-coupon available. I saved almost thirty bucks on a Mighty Mite Blue Burst Jazz body. It was on backorder and I had to wait about three weeks for it to come in, but my patience paid off.
As far as the neck goes, I've got my sights set on a particular Squier bass neck. I'm waiting until I can get a scandalous deal on a used one. Then I'll harvest the neck, make a small modification (I wanna gloss up the back of the neck a little bit) and sell off the loaded body to offset the total cost.
So, if I were trying to replicate Geddy's green Custom Shop Jazz on a tighter budget, I'd grab the neck off a Squier Vintage Modified '77 Jazz bass. And if I wanted to go "all the way", I'd seek out someone with the skills to match the headstock to the body. http://www.fender.com/squier/basses/...-jazz-bass-77/
