Is there a good compressor under $1000 usd that will fill 100 cu. ft. scuba tank efficiently?

If there is a problem I can’t take care of on my own, is there repair service for the GX pump in the US? Thanks.

Target Forge sell parts and may do repairs as well. I also think there is a member here who does repairs. He'll probably see this and reply.
