Thanks for the link Mr_Odwin.
Only read a bit of it, but it appears to be a bit of a mixed bag so far. The main problem seems to be distortion due to the reduced tube size, it's not supposed to be very noticeable but I get a bit of that in the corners on my current TV and it can be annoying.
Anyway, I'm going to see if I can check it out in a shop first and base my opinion of it on that.
