I see why people don't like Rega Planer 3; it doesn't sing until after you do all the tweaks, but does it sing?
I forgot how much money because that was over a period of time, replacing the tone arm wire was tricky and required a bit of skill, but that was the biggest improvement; beside the motor of course.
Nevertheless, after all of the tweaks, it's no longer a Planer 3, and I wouldn't trade it or sell it.
