The way that the SL1200 implemented direct drive is what makes the SL1200 top-dog for DD tables! Also, the quartz timing method can't be beat!
If you are a DJ, you need a table that can come back up to speed very quickly, so DD is the way to go.
I have a DD SL1210 and a BD Pro-Ject Debut Carbon.
Overall, I prefer the SL1210. But, it was also almost 3x the price!
Also, I have spent my younger days in the clubs and had friends that spin vinyl. For me, the SL1200 series is iconic!!! I would never, ever sell it, it's a permanent part of my collection. It does more right than it does wrong, it's built like a tank, and parts and expertise for repairs and mods are readily available.
My 2 peeves on the Pro-Ject: The cheap looking anti-skate device (discussed in another thread), and the wall-wart power supply. One day, I'll get around to either buying a speed box or building a motor controller. On the other hand, the Debut came with a $100 cart installed, has a carbon fiber tone arm, and the finish of the blue model is immaculate!
I would and I have chosen the SL1210 or the Pro-Ject Debut over the Onkyo hunk.
