Far better it is to dare mighty things, to win glorious triumphs, even though checkered by failure, than to take rank with those poor spirits who neither enjoy much nor suffer much, because they live in the gray twilight that knows neither victory nor defeat.
― Theodore Roosevelt
I do keep an eye on the gunbuster auctions (and just got a parts kit for Taurus 856, with spurless hammer). But, hard to count on finding anything in particular. Kind of like going to a gun show -- be ready to buy, or walk away without regrets.
I'm thinking if the ebay listing meets his needs, he should jump on it.
