Cheers! I think it is just like @Grangursaid, that time is needed in the preparation to get a good starting point. I do like Morrells sprays, they seem to give a fine, uniform spray and don't 'splutter' in my (very limited) experience.
I'm very inexperienced when it comes to spraying things - I do have a small compressor and cheapish spray gun that I have used when applying water based lacquer on a few builds. I've had reasonable results but It's something I would like to spend more time practising - I'm really impressed by professional sprayers and the finishes they get. You could build the nicest bass from the best woods but a poor finish will make it look poor.
I guess it also helps to have plenty of room, a booth and decent equipment but this is something out of reach for most of us and probably the reason we often opt for wipe on finishes like oils!!
What sort of set-up are you thinking of or trying?
