Learn to cut yourself and it pays off.

That's probably $400 worth of clippers right there but I've had them almost 8 years and they pay for themselves after 20 cuts. Trill talk, its not hard at all to cut a ceaser once you practice for awhile. Now I can cut my line-up as sharp as a barber. It has nothing to do with the blade sharpness but the angle. You gotta grip it a certain way, etc.
Only tough part is fading. Ever few months I'll go to a barber and get re-calibrated. But I hate when barbers push my line back or cut my hair too low.
