Getting 'no heat' out of the dryer. Should I just buy a new one or repair the unit?

Disconnect power and pulled the lower front panel off unit (2 screws).
I used a ohm meter and found heater coil open. Ordered correct part online (easy to find it on the web site).
Three days later, new part in hand I unplugged the failed unit's wiring and removed the heating unit (2 screws). Installed the new part, connected wires and reinstalled the four screws.
Engaged power and turned the dryer on. Vent pie had heat, so placed wet clothes in unit and ran a dryer cycle. Works like new. Cost was about $65.00 versus the $500.00 for a new dryer.
