but I've not had experience with any of these guns, it does say in the other listing you singled out that you can get spares for the other type (I'd imagine it might be possible with the other type too though).
I would go for the stainless pot'd one though, the plastic cup types are ghey to clean and it has smaller nozzle which will give you the edge coverage better by leaving you with less work feathering the paint out.
Like i said, havnt had any experience with either though.
ake sure whatever you for for though, that the compressor you use is drained first (unless you have an inline filter), as smaller nozzle guns really blat the moisture in the lines out and can ruin a nice job

The sealey filter is by a mile a better filter for the job
I'd still purge your tank before spraying anything of course but I've seen tanks purged in the morning and by the afternoon have enough water in the bottom to fill the 3 1/2" silverline.
You could use both but you dont really need it, the sealey one is good enough
