i've never owned a 100LG, so i can't answer your first question, but the ol' badger pro (MikeV) should be here soon. i will add this though, you should only breakdown the airbrush after say............25 hours or better of use. if you flush it well when you finished with each painting session, you shouldn't develope much paint build up at all. breaking the brush down after each session just causes unecessary wear and tear or the chance to lose/damage a perfectly good part. believe me, i too fretted over how clean my airbrush was many times when i first got my airbrush. but after having one and getting used to using one, it seem that the "dirtier" she gets, the better she performs!!LOL now i don't mean leaving dried paint in there, but i just shoot the appropriate thinner through until it comes out clear, and put her up or switch to the next color.
but the other question, dixieart sells a set of micro brushes that simply can't be beat for cleaning an airbrush of any type. i bought the set that comes with 6 microbrushes (i think) and the tiniest brush is able to go through the tip of most brushes. good luck with your new purchase, and may you experience many wonderful hours of airbrushing bliss my friend. later.
