If you're considering Sterling by Musicman, you should know you might probably be able to find some USA Stingray5 used for a little over your budget (1200-1300$). IDK, in that scenario, spending 800-1000$ on a new SBMM doesn't seem that smart to me (if you can afford the slight over budget, of course). As per other 5ers under 1000, I have experience mostly with Yamaha BBs and Ibanez ATKs (owned several of both), all solid options, available in a variety of price ranges under your 1000$ budget, high quality at any segment. The 2 under 1000$ 5ers I own now are a Schecter CV-5 (best Fender killer I've owned, can be found in the US for around 400$) and a Warwick (Korean) ProSeries Star Bass 5 (IDK about these in the US, got mine for 600€ here, the current Chinese RockBass model is almost equally as nice).
I'm not counting Maruszczyk, which is one of the nicest options you'd have here in Europe within your budget. I've had a Maruszczyk Jake 5a+ that I got for 850€ used. You can often find a Jake or Elwood in the 800-900€ range (as of right now 1000$=882€). But I know in the USA these are hard to come by and more expensive.
