servo vs stepper

As many have read, I have been having a bad time making stepper
motors work using Gecko drives. Several have recommended switching
to servos but I have been fearful of tuning the motors etc. Is it
really that difficult and that much more expensive? At this point I
have spent $550 on each motor. I am also concerned about the
difficulty of selecting the correct servo motors since I have had so
much trouble with the stepper motors. I guess I would appreciate
some encouragement or discouragement at this point especially from
those of you that have done it with a Bridgeport. My machine is a
Boss 6 Bridgeport.
