Hi, T Bone - Very glad you had a successful recovery from your illness. As to an air compressor I use a California Air Tools, over the years I've had several others, they worked and held up well, but THE NOISE. This one is so quiet, just about speaking voice level.
It may be overkill for you, twin piston cylinders and large volume tank, bought at Home Depot for about $180. They have another smaller model, single piston with tank, even quieter, I think it's the 1060-S model, about $110. Check you tube, there is a demo of it running with comparison of another compressor. Dramatic difference. Highly recommended brand.
For paint I use Tamiya acrylic, the only others I've used are Polly Scale and Vallejo Model Air. I always have good results with Tamiya, super easy to use and dependably smooth finishes. Have heard very positive reports of Mission Models, not available to me, I plan to order some for a trial.
Good luck with your getting started painting again.
