If you want real highspeed sync ;-), look for one of the various early DSLR's with hybrid shutters (the mechanical portion never exceeds physical flash sync speed, with the higher shutter speeds acheived electronically on the CCD sensor). IIRC the original 1D had one and the Nikon D40, D50 and D70 did. They can provide hardware sync at 1/4000 and higher (1/12000 for the Canon, 1/8000 for the D70). Biggest problem becomes getting a short enough duration on the flash burn, most Speedlights have a ~0.5-1ms burn at full power, far too long for these cameras with shutter durations of 0.25ms or faster.
Note that flash duration becomes a serious issue at high sync speeds, which is why HSS is actually a better solution in most cases. The Nikons with high sync speeds were all software limited to 1/500 with TTL flash to allow a full-power burn to meter correctly.
Where leaf shutters come into their own (as do hybrid shutters) is when shooting low/mid-powered flash burns outdoors. Flash power is modulated via burn duration rather than intensity, so a mid-power firing happens quick enough for your leaf or hybrid shutter rather than the shutter cutting off the end of the burn....Show more →
It's a good point about flash duration. There are a number of options though, some not so expensive.

I would go with this Profoto if money were no object. 1/25,000 sec flash duration...Ya Baby!

The great thing about being able to shoot at very high shutter speeds is, of course, one does not often require a lot of flash power (and thus will be getting faster flash durations when using less power).
