Hi Shaun
I've also dealt with Lamoore as a buyer not a seller. In fact I bought my Mk III Tails, through them and they were very professional and accommodating and would take me out most Saturdays to look at the top hats they had at the time. They were very aware of my relatively modest budget (compared to the larger yachts on the books), but I always felt like I got their full attention and nothing was too much hassle even though i'm sure I was pretty indecisive at the time!
I would certainly go back to them again from a buyers point of view.
We also had some dealings with David Bray over in Pittwater too. Mike King took us out a few times and gave some very good advice on top hats (having owned one himself a few years ago). Mike again, was very professional, friendly yet experienced and nothing was any hassle for him.
These are the two main ones we used when looking at the time and had a good experience with, from a buying point of view. But both were very tophat friendly
Sorry, but no experience with the selling side of things.
Hope that helps though
