Have no regrets TTSH, you did absolutely the right thing, which was to walk away. Hey, you already have one! I know, I know "more is better" but that 4506-1 just might appear tomorrow or next week and then what are you gonna do? And by the way my 4506 no dash is my favorite 3rd Gen.
By the way TTSH, YOU ARE THE ONE who provoked me into putting on lay-a-way an unfired 4566! Remember that? Lol. And, I'm VERY happy you did. I should have it in a few weeks. In case you forgot you can re-read your comments in post #6 in this thread.

Sure wish you could shop the stores and pawns out here, they seem to always have a 3rd Gen or two in stock. I've even had to temporarily ban myself from entering these establishments. until I've reached full recovery.
