Like others[Pres.,Mark C,
I have a Brent CXC.Bought used in Seattle 35 years ago. There was a grinding sound about 2 years ago-no,not my Mother -in-law.
Anyway, our shops teacher in high school replaced the bearing.[for about $20.00]. The wheel works GREAT! Unfortunately, I bought a lighter Brent to use in the interim. Can't remember the letters. The wheel has a quicker response time, lighter to move around,etc. I have often thought of have the two wheels in my shop. Taught one of my sons how to throw on it over Christmas. He picked it up way faster than me. I think I will keep one for decorating and one for trimming and throwing.If I were to buy new, I would probably buy a Whisper. Does this help, or make your decision more difficult?
