I don't know anyone who has a Q'nique, so can't comment on that. As far as the frame goes, though, if you think you might, someday, maybe, possibly make a king quilt, get the bigger frame.
Lights over the frame are wonderful, as they make it easier to see the entire quilt while working. My DH put a flourescent shop light over my frame. I love it! My set up is in my garage, so the beauty factor for the lights was not an important issue, compared to price. However, the cost to purchase and put them up ourselves was minor compared to buying the overhead lights made specifically for over quilting frames. And my lights don't move.
I hope that helps. I think Q'nique has been discussed on QB, so maybe if you do a search for it, you will find people who own one who can help you.
