Here's cheap: a starting cap & a push button. Wire the cap & PB in
series between either line leg & the generated leg. To operate: push
the button, turn on the power, when the motor is up to speed release the
button. That's how I use an RPC on my mill & it works fine. It is not
balanced, but balance is not something I need, nor do you, in all
likelihood.
