Lot's of newbies think electronic is better but the Stringway drop-weight with TRUE constant pull to the correct tension AT ANY ANGLE is superior in my not so humble opinion. Electronic motors wear faster than a steel weight on the end of a steel bar with steel cams in the interior of the tension device. Nothing as consistent as heavy metal and gravity. For $, this is best machine on market.
