Im not one to judge things too much on their cost, but I feel weird installing an inexpensive gyro in a jet.
You'll be happy with the ACT gyros then

Having said that, I've just checked their website and, I'm not sure if they have lowered their prices, but they aren't too badly priced at the moment.
Made by ACT in Europe. Sin City Jets have sold ACT gyros in the past.
