hello and welcome to the forums
HAHAYOUDONTKNOWM!!
i had an aztek as my first brush and it caused me no end of problems[:0]
...then i dived into the airbrush/painting forum and came out with an iwata hp-c (i think!...it was definitely iwata anyway
)...
...and now i'm happy!!
check out that particular forum, as you'll get the best advice there; hope this helped.
regards,
nick
