I feel your GAS pains.
I’ve got a SUB Ray 4. I agree it’s very good value for money, and is very amenable to upgrading. Plays great.
The Stingray 24 is made in Indonesia (like my SUB), and has a similar ceramic pickup. It lacks the belly cut and forearm contour, which might make it less comfortable.
The EBMM/SBMM/Sterling ranges are very confusingly named and differentiated, to be sure, but I think you probably can’t go wrong with either of the above basses.
