Need a new air compressor

I got an omega about 6-7 years ago,3hp i think. I dropped a few bucks on a decent gun for my sandblast cabinet, made a big difference in air consumption.
I know itsa bottom of the barrel compressor, but it does all i need it to. I have a second air tank in the next building with the line buried. But quite a small line.
My needle scaler uses a fair amount of air, and i dont think i will ever use it in my shop again. That exploded rust pollutes every nook and cranny of the entire shop.
My compressor gets fresh air pumped into a cabinet through an air filter.keeps noise down and cabinet doesent get too hot as air is constantly moving through.
