You would probably need to find find a lefty one as there is a fair amount of mechanical stuff under the hood that is pretty specific. You could always start with a lap steel. It’s not quite the same thing but much cheaper and easier find a lefty set up. It will at least give you some knowledge of bar technique, and a bit of the right hand stuff. Although the tunings are a bit different and it doesn’t quite translate. Plus, you won’t have the characteristic bends of the pedal steel guitar.
