Accumulate whatever you like and whatever you can afford.

The heck with what others say or think or do. Only YOU have to be happy with what you own.

What you've described is almost exactly what I've done the past 10 years or so. Sure, I've got a few "new in box" but really prefer 95% condition guns I can shoot. Now that I've been at it a while, I find myself getting rid of some duplicates and more common guns in favor of higher-end, more obscure or rare/odd items.

Have fun and just roll with it!
