My biggest complaint is the piece of crap felt platter mat that came with it! Just be ready to upgrade that, about $25 for the cork mat or $125 for the Acryl-it platter. Nit picking, but for ~$400, surely they could have included a better stock mat. This was the Debut Carbon model, I think your XIII came with the Acryl-it platter so you didn't have to worry about the mat.
The other thing that I don't really like is that I can hear the motor when I turn it on. If does NOT get picked up by the stylus and does not get amplified and sent to my speakers (thankfully), but if I am standing in front of it, I can definitely hear the mechanical motor rumble. Once I'm about 3 or 4 feet back, I can't hear it at all.
Of course, mine is not the DC model, mine is driven directly off the mains power frequency. I'm curious if the DC model has corrected that.
All in all, fairly minor complaints for an entry level TT. I just think looking at the price etc, maybe I would have been more satisfied with the U-Turn. At the very least, I would have been satisfied by supporting a small American-made company. But, at the time, I thought the Pro-Ject would be the safer bet, and it did come with a much better cart.
I have considered selling it, but then I would probably be out $100 as compared to the new price, and I would likely have to spend at least double the $ to get huge improvements in performance, so I just keep it and use it.
I do prefer my SL1210 TT. But I could not get a Q-up to install correctly on my SL1210. Having the Q-up is a HUGE advantage for a fully manual TT IMO.
And, the Fit and Finish on the Pro-Ject is very nice!
