Hobby spray paint gun

Does anyone have any recommendations for a simple spray paint set-up (not too expensive & easy to use)?

After doing brushing on a primer coat & first coat of paint, on dining room chairs with many grooves - ie. routed out areas & scrolling - I realize that I really need to spray them. I would also use it for other decorating projects & for painting pots - figure I'd have more flexibility about colors & probably save $ on paint.

Any ideas &/or wisdom are welcome!

TIA,
