I will recommend the Sparmax DH103 for general purpose modeling. I hope that Phil H will see this thread and post his opinion on this. Any of the Sparmax compressor on the YY&Van page should work fine for you.
Hmmm - I seem to be the only person on this forum who uses a Sparmax brush.
I can't speak for the DH-103 as I haven't used it, but I do use the SP-35C which is very similar (The DH-103 is a 0.3mm nozzle and the SP-35C is a 0.35mm). It's a nice little brush, well built and having a decent weight to it. I've used it for about 4 years now and never had a problem apart from the occasional "tip dry".
In the time that I've had it, I haven't bent or broken anything (touch wood) and only had to remove the nozzle maybe three times (once to clear a major blockage). I think, though, I may pick up a spare needle and nozzle when I get a chance.
Using acrylics exclusively, cleaning and maintenance is quick and easy, most cleaning only requiring a wipe of the cup, backflushing and spraying clean thinner through it. When more aggressive cleaning is required, I just put a few drops of lacquer thinner through.
It will handle most any task you will encounter in modelling (assuming you have a steady enough hand). I've even tried freehanding the rubber tyre portions on a 1/72 Pz IV wheel as an experiment and had passable results. Someone with a steadier hand than I may have better results. Control is very fine and very linear, meaning that you have a decent range of control and won't get a sudden flood unexpectedly if you move the trigger just that tiny fraction of a mm too far.
The only real problems I have is with (Tamiya) metallic colours because the metallic flakes in Tamiya's paints are quite coarse and can cause blockage.
Here in Sydney, the best price I can find (ironically, at Sydney's most expensive hobby shop) is $82.50 at http://www.hobbyco.com.au/product/show_item.php?plu=SPSP35C
The DH-103 mentioned above is $79,95 http://www.hobbyco.com.au/product/show_item.php?plu=SPDH103
Most other specialist airbrush suppliers here in Aus seem to have these brushes listed in the $125.00 - $139.00 range.
