I use a Thayer&Chandler Vega2000 and its perfect for applying base coats down to some really small tight camouflage paint jobs which I do on my 1/72 Luftwaffe aircraft , its also really easy to clean breaking down into three seperate parts which take less than a minute to clean each! It was also reasonably cheap to buy costing me only $42 US from bearair along with a fine needle and nozzle which only costs a few dollars!
You should look into purchasing one!
