Is anyone using V3 successfully yet?

My main site is still on v1.3.5 because it has worked over the years, and continues to bring in business and easy to manage and customize. I've tried lots of different V2 releases but found too many issues and didn't migrate very well from the V1 site. I have since decided on V3 ultimate and looking to move to that but haven't got it working yet, and just can't get it to look right. Just wondering if anyone has a working V3 site using either the only template bundled in, or via a 3rd party template? I would like to see what can be achieved realistically.

I'm worried about buying a 3rd party template that breaks as soon as another CS Cart release comes out, and the only template bundled has too many design issues for me and difficult to get right.
