One of the favorite 120V air comp for tire airing >100 PSI is
Porter Cable CMB15
It won't run air tools but otherwise very well liked - considering getting one myself - only $99 online. If you need more capacity the slightly larger PC pancake comp is another favorite w/ the RV community.

Other similar VAIR models available at various price / performance points depending on what you are looking to do
