Beginning new hobby

i'm trying to get started in painting...

i wanted to know if there's a decent quality, bang for the buck sort of kit to get started? like a respirator, gun, all the accessories all-in-one?? (i know there's some on ebay but i dunno the reliability of em)

or can you suggest some brands for all the equiptment? I'm looking at devilbiss or sata guns(any good?)

so basically any info for someone starting up would be helpful... thanks
