a respectable mourning period for your dear departed cash?
if its one I really want and its in the budget I'd go for it
but as Dean says - you can't buy them all- I like the next to be an interesting addition - I see them nearly every day either in a shop or online that I like and think about, but in general it would need to be something I don't have.
then again - i am a shooter, not a collector - so each needs a use.
