A while back I bought the new Lee XR/ERGO Replacement tray. To be blunt, it's a piece of junk, you always drop primers trying to fold out the tray hold it flat and put the new primers in. It's just cumbersome at best to use. I've gone back to the old tray, which lost a corner, using a couple of rubber bands to hold it together. I would like a decent flat tray like the old Lee tray. I don't want to have to buy a whole new set of case holders, I have all the ones I need, or could want later. Is there a 3rd party tray I could use, that uses the Lee case holders?
