I'd say initially - go for a MIJ/CIJ, but............if you find a mexi jazz that does it for you - looks, feels and sounds good - then go for it. A MIJ will always have a better resale price, but you can't beat buying a bass that looks good in the flesh, and by playing it, you know has no deadspots or other issues.
If this bass is gonna be your 'one and only' please..... don't trust to a mail order online sale - try before u buy!
