I love my Sterling by Ernie Ball Ray 35 - got it for £650 used from eBay.
Active, 3 band EQ, sounds like a StingRay, looks the business... I love it.
The SUB Rays are substantially cheaper (£250-300 ish s/h) and are pretty well regarded, not sure if they're active though.
Harley Benton stuff is absurdly cheap and (by all accounts) really good quality. Their 5 string StingRay knockoff is less than £200 IIRC.
