Max shutter speed with external flash I have an old Nissin external flash that mounts with a bracket to the underside of the camera via tripod mount and the maximum shutter speed I can use before the shutter curtain shows up in the photo is 1/250 sec. Can anyone tell me what the fastest shutter speeds you can use on the latest TTL external flashes like the Canon Speedlites or other brands like Sigma?

Marius, the fastest shutter speed that can b e used with electronic flashes does not have to do with the flash, but with the shutter in the camera. In cameras with focal plane shutters, the fastest cameras are able to sync with flash at 1.250th; most cameras actually get shutter curtain interference above 1/125th second. Old times may remember that leaf shutter cameras (like the Hasselblad medium format) were able to synch to flash at faster speeds - some to 1/800th second - but this is because leaf shutters by nature expose the entire frame of film (or CCD) at one instant, whereas at high speeds focal plane shutters expose the frame with what amounts to a slit moving across the field. So, I do not believe you will find any other flash that will allow you a higher sync speed, since the flash really has nothing to do with it.

Canon EOS digial cameras and their later model film EOS bodies support FP high speed flash sync with their EX-series speedlights and some 3rd party compatibles like Sigma's EF 500 DG Super. The compatible flashes will continuously strobe as the shutter curtains cross the image plane, allowing flash sync at all shutter speeds.
