First of all, thanks to all of you for your input. There's several things here that I hadn't thought of.
Buying pipettes in bulk is a good one. And I have a bunch of 35mm canisters already. Don't shoot as much film as I used to but there are a lot of empties around. There's a couple tubes of BBs in the gun cabinet. I think I'll invest in one those little mixers too, sounds like a good thing.
One thing that bothers me about this is the amount of paint that gets wasted in all the transferring and handling. I guess that can't really be avoided though. Let me ask you a couple of other things. Is there a shelf life for paints? Is it ok to thin a whole bottle of paint at once and save it for future use? Maybe I'm way off here but that seems to be a way around wasting paint by thinning a little at a time.
On the other hand, I saw a mixing system in FSM that used syringes that could be coupled together for mixing or thinning your paints and special caps for the paint bottles. Evidently there is even a cap that you can use on the syringe to attach it to your air brush. I know, I know, more money and more things to keep up with but if it works as well as it appears that it would it may be a good investment. Here's a link to the site.

And I do keep my tools clean. I live in an apartment and any way that I can lessen the chance for a spill or splatter is a major concern. Thanks again for the tips and my apologies for taking so long to return. I was here the other morning after work and fell asleep at the keyboard. hehe
