newbie question about guns

[martens]

Right now I've got a couple of old binks pressure pots and a mach 1sl  and a model 62 that I've been using but I mostly do small one off projects and the clean up sucks. Sometimes I spray 3 or 4 different finishes in a day so I think I'd be better of with a sata gun...right?

I found some used sata jet  guns for sale in town....
Sata jet 90's.1.3 tips one HVLP and one  RP also a Sata NR mini jet with a 0.8 tip.

Any of these guns work for me?
I do 60% laqure and 20% stain and 20% solvent base paint.
