im needing a good overall gun i learned on a sata and always lke them i found these for much cheaper. https://www.ebay.com/itm/PAINT-SPRA...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649 are they legit? and can the rp be used for mettalic base coats such as silver if they are turned down? if so hows it do for base? if not ill probably go with an lph 400 ill probably have to get used to its slow spraying though.
