Yep. I do not need ~20, but I became a bit of a collector when it came to pdib's wooden ones (no two are alike) as well a CeeCees (I have one in every material he's made 'em from).
From a purely utilitarian standpoint, 6 mech squonkers would be entirely sufficient, particularly with if one has a small stash of spare parts in stock (firing pins and negative springs for REOs).
If you like Grands better than P67s, my guess is there are people who would trade...
You know that Corey can make his style of firing pin (with the solid silver contact) for REOs, right?
