RE: how much do you spend on servos
If I could get any servo cheap it would be an entry level digital. Unlike the US the VAST majority of planes in Aus are .40 to .90 size.
I would really like to get a cheap servo with normal sport servo torque (50 to 70 Inch/oz) but a faster transit speed (about .1 sec) Digital would be a bonus. If you can make a servo to these specs that is cheap. I'll take heaps of them.
