i keep an adapter threaded to one wheel of my presta equipped bikes. i do have presta hand pumps, but if i'm swapping in new tires or tubes or making repairs, i use my senco 4.3gal oil bath/dual tank. it's so much easier. plus, i can give the bike a good blow off at the same time if it's a bit dirty. are you trying to find enough justification for getting a compressor or something?
