I got a very cheap one with a separate compressor and hose, works fantastic but I did trip over it quite a lot. I see the “for makita” cordless invasion is well and truly on for these, I’d be tempted to try that just for the convenience. Sometimes I found the paint seemed to sort of “sit on top” especialyl when I was doing some previously treated wood, I ended up basically spraying on and then quickly brushing over just to sort of work it in, on those bits which was a wee bit annoying but still miles faster than brushing or rollering especially with shapes and edges and such.
The main thing is to be quick on the cleaning, lots and lots of water, especially at the cheap end where teh “needle” is usually plastic. It’s very, very helpful if it comes with a separate lid for the paint tank, so you can just seal it up between coats or jobs rather than having to empty it every time, I think most decent ones will.
