In my stringing lifetime I've used a dropweight and a crank. After a short stint with a dropweight, I moved on to a crank. Went thru several upgrade with the crank and have used it for over 15 years. But, just this week moved onto a electronic.
A crank will fill your needs better until the urge strikes to move forward.
If you decide on a crank, email me. I might be able to help you out.
