So I bought a Vector Optics Continental x6 5-30x56 and a Falcon S40i+ 4-40x58i FFP. Both have quite nice glass. The Falcon snaps in and out of focus better than the Continental, but the Continental has better definition... or maybe focus's better (both at 35m) - either way it's a clearer picture, but neither are exactly scratching the itch. I've pulled the trigger on Javelin x30 and I'll compare all three again when they turn up.
I keep looking at the Element Optics Theos, but it's a hell of a jump and would require selling a lot of bits. Hoping the Javelin does the job.
I've also got a good deal (I felt) on a Caldwell Precision Turret Shooting Rest from here -
