It seems that we were either very lucky or at least, in the minority.
We couldn't find a second hand boat to our spec (60' max, 3 bedrooms) so had to go for a new build. Had to wait a year for the build slot but we weren't in a rush so no probs there. Found a small family run business in Chorley, paid in stages (we had to remind him when payments were due!), Liverpool hull.
Boat ready on time and much better fitout than we were expecting for the price.
Lived aboard for almost 10 years now, only moving into a marina with hook up last year, and no problems at all!
And before you ask, the boat builder has now retired, sorry.
