Big +1 for RCBS Universal Hand primer (square tray). I still use my old lee for small primers (only one cartridge I reload takes those, and I don't reload very many of them).
I suggested last week on RCBS' website that they come out with an RCBS Universal hand primer "add-on kit" which would consist of just another handle without the primer punches, primer guides, tools, or tray. That way, one could just use the extra punch and guide from their Universal Hand primer, and have two handles ready to go (the tray just slides in/out of the handle, and could be shared easily between them). Haven't heard anything back... maybe if more reloaders suggested the same thing?... Failing that, I asked how much for the parts to assemble my own extra handle (prolly more than a whole 'nother unit)
BTW, for those who have the older, round tray model, and would like to use the newer square tray (it feeds better from its corner than round trays do), RCBS also offers a square tray upgrade kit. The larger square tray also lets you set a factory sleeve down inside it, so that all the primers come out right side up without even shaking it.
