Yes, cleaning them after each use and adjusting them again before each use is a hassle.
But when you need to spray and want to cut cost....
You need a compressor 2-3HP compressor 8.6 CFM @ 40PSI.
HVLP sprayer ... Sears or Husky or Harbor Freight are about the cheapest
Lots of lacquer thinner...
One other problem is ... it is a big hassle, irritation and nuisance to spray one small item,
ya know, one coat probably don't cover it so you gotta wait for it to dry. Meantime, your
spray nozzle is drying also.
You need more than one canister so you can switch from lacquer/BLO to your cleanup
(lacquer thinner) canister.
I spray a lot but find ever now and then, the rattle can is so much handier for a small, single
project.
