I’m a home Stringer who does around 800 rackets a year. I started with a gamma progression ELS and upgraded to a Wilson Baiardo a couple years ago. Contemplated selling the Gamma but kept it just in case. Just in case happened yesterday when myBaiardo‘s power supply bit the dust. I had four rackets to do and thank God I still have the gamma. Ordered the new power supply for $250 (yikes)and it should be here within a week.
