I love SR basses too. I also agree that most of the Fender-ish necks are a bit chunky compared to the Ibanez profile. That's why I suggest Peavey Foundations. Their necks are in the same vein as Ibanez and they are still severely undervalued. Being an lover of all things Ibanez, I'd also suggest looking for a ratty SR500 as their finishes were notoriously fragile but the necks and sounds were still amazing (never mind, seems the prices have now caught up with the quality...sadly for me). Either way, patience will net you the result you desire OP.
