I have painted minis in the past...but the VAST majority of my metal minis are gloriously unpainted, and have been since I got into the hobby in 1977.
That's true for me too, but usually I try to have
my character's mini's painted at least crudely. Although I'm guilty of being a non-painter, I appreciate things in this order of art appreciation:
MOST APPRECIATED: A painted mini with turf-grass and clear-plexiglass elevation systems for flying and flags demonstrating when raging or invisible..and supplemental prone painted mini showing "MAN DOWN." Additional weapon attachments are nice and can be used to show when disarm or fumbles have occurred. A mounted alternate character is necessary, with camel and horse variations for different mounts. The players table tent drawing should match the picture of the character and if possible, a short-google-movie on "THE MAKING OF THE MINI" is ideal.
APPRECIATED: A painted mini or "CARDBOARD HERO" resembling the character, even badly painted or chipped paint, that stands up and is to scale. It greatly helps the DM FIND the character in question during the game, and the color (any color) adds to the gaming experience.
SOMEWHAT APPRECIATED: An unpainted mini that at least stands up and resembles the character. OR, a primered mini (best if there's one quarterpanel that is a different color of primer to demonstrate what a big REDNECK GAMER YOU ARE!!!

For sheer mechanical purpose only, this is the 'minimum' to demonstrate you have any interest in contributing to this portion of the hobby.
'MEH': Pogs that resemble the character. They're hard to pick up and move in complex situations.
LEAST APPRECIATED: An unpainted mini that neither resembles the character, nor can stand up 50% of the time, nor is to scale, nor has any business.
NOT APPRECIATED AT ALL (DEMONSTRATES A LACK OF ENTHUSIASM FOR THE HOBBY): A penny or die or worse, moldy candy.
From the DM's side, I've got boxes of warhammer orcs that I use that will never be painted..although I did give my 3 year old a try at the zombies and they turned out pretty good. Kind of a snotty-creamy pink

I think that scares the players more than a well-painted zombie! I've used clay and rocks in recent games as well as the occasional child's toy for demons (nothing better than beenie baby demons!!!) In cases like this I'll usually have a picture from GOOGLE printed out on a sheet of paper so that they get a better idea of what it looks like.
Do your "appreciation levels" match mine?
