Vector animation software?

i’m doing some basic 2d animation and flash is very irritating to work with (nested clips do not update frames on root level, paintbrush can’t be resized thru shortcuts, eraser can’t be resized)

I like the way flash is way simple to handle, but unfortunately it doesn’t cut it for some projects

do you guys know any good vector animation software ? (preferably free, but I’m willing to chip in 30 euros or so)
