The Seires III necks from Selmer are a pretty good way to go. They're a tad loose but a good pro can expand the tenon to fit. Or, Emilion Lyons uses just the tiniest bit of nail polish on the tenon to get a snug fit. The only thing I don't like about the necks is the octave pips are a much smaller diameter (at least on all the ones I've seen) and I think this pinches the sound in the palm keys a little. You can have a good technician open it up to spec and it should work great.
