If you dont mind spending some extra money then I'd buy the Iwata LPH400 with the purple cap as well... VERY nice gun and it lays the clear down like no other gun. Accuspray is OK for the cheaper guns and you can use it. If you plan to spray a lot of stuff or heck even if you wanted you can buy it, hold on to it and sell it later.
I am surprised how many people here are liking the Iwata, most people I know say Sata (which is a very nice gun too) but I like the Iwata most.
