As much as I hate when people on forums try to talk the original poster out of their stated goals, I also think going for a top loader is a losing battle. Dedicated CD transports without onboard DAC are already rare these days. Top loaders are also very rare. Combining the two makes your options extremely limited.
Anecdotally, I know one person who had nothing but trouble with the Pro-Ject you mention. It looks cool though, and you know Pro-Ject will be around for a long time. I always thought they had good support, some posts above indicate otherwise though.
I also know someone else who had problems with the Jay's transport, although it was the mark 2 not 3. They eventually got it sorted after a frustrating delay. It would be tough to trust a company with one dealer to support things long into the future.
If it was me, I would look at other non top loaders like the Teac mentioned earlier. I'm also intrigued by the Michi Q5 which is a top loader that has a DAC on board, supposed to be amazing. I know probably not the answer you want to hear, there just aren't many options that fit your criteria.
