I've checked the prices before writing. Thomann, i.e. the European Amazon of Musical instrument and the de-facto price standard sells the Stingray for 2290€ to 2600€, i.e. from 2600$ to 2980$ (Invalid Link Removed) while the Fender Flea goes for 1690€ aka 1935$ (Invalid Link Removed).
We are talking about a difference of 650$ bucks at least or tu put it in perspective almost a 30% price increase with respect to the Flea. I'm not sure if the two are really comparable but still the Flea looks to be a really nice bass.
I'm unsure if in the US the price difference is not so big but 600$ are, at least to me, quite a lot of money.
By the way if you'd like to be super savy wait one year and buy one of the two used.
