another compressor question!

I have painted quite a few cars over the last few decades, BUT I claim to be NO bodyman.
long story short, I moved to Tx last fall to be with the love of my life, sold about everything, and of course, have picked u p a couple of project cars! ha
we will sell this place here in couple of years, and I do not want to invest in moving power poles, put in 220, but I do want to spray some paint. SO NO big compressor. do not need to run DA, file, etc ha...
which is the best bet and sense $ wise... ? invest in one of those, what you call them? turbo systems????? OR , go with small upright tank and low output compressor and gravity HVLP gun?
in the 70's I saw my dad prime and pant my inline horse trailer, in F8 met. with a Sears 10-15 ??gal compressor and gravity gun. laid it down good as anyone . thanks.
