I think you've answered your own question. If 
you're feeling pickier then you'll probably be 
happy with funds to spend on "better" (or at 
least more to your current taste) cels.

I reached that point a couple of months ago and 
decided to part with a few.  It wasn't the 
easiest thing in the world to do, but I'd had two 
years of enjoyment out of them and they've made 
other people happy now.  And as long as you're 
not parading them around as yours but clearly 
mark them as your "former" cels, there's nothing 
to say you can't keep those nice scans forever to 
look back on. :)
