obviously u have either not equiped urself with much readings or unable to understand just by reading alone.

no worry. u just need to get some real modelling frens to show u the real thing.
i had many readings before i got my ab and compressor and stil get the wrong concept
ab gun/handpiece
not really much thing u can choose except for the price u willing to pay for and brand.
other specs are quite standard line:
1) nozzle (0.2mm, 0.3mm, 0.5mm, 0.3mm being most commonly used, 0.2mm for spraying fine works and 0.5mm for broad area)
2) cup (cup size and cup location, on top, bottle feed, side feed, up to ur working and own preference)
3) single or double action

compressor
1) compressor/"engine" type: fridge type (round heavy black, and is expensif) or normal hobby type with metal heat sink cooling fins (looks like motorbike engine)
2) with or without airtank (with air tank u no need to worry about turning on and off, as the one wt airtank usually come with auto on-off switch)
3) pressure regulator and mositure trap (standard must get items)
pipe or hose, need to ask meh? when u buy compressor just make sure got attached hose, don have then get one lor.
nothingelse.

You'll need at least the FilterTouch. The moisture trap will be important, unless you've got some other external moisture trap, like what I saw in another post in the garage sale.

These compressors do not have an air tank. It's recommended that you let it rest every 20-30min, and not let it overheat.
