I'd Buy high condition even if it were a shooter.
I think you can usually keep a 98-95% gun in that condition as long as you don't holster it and wipe it down with Hoppes #9.

So a K22 first Model. Or K22 3rd Model, or a Heavy Duty would be high on my list.

I had a 98% K22 that I shot a bit without degrading it's condition. Don't clean the bore too much or you will accidently put more wear on it than shooting it.

I'd definately be a condition shopper if I had $1000-$1500 to spend.
You get a shooter and a collector all at once. Always buy "condition" is my way of thinking.
