Why not an Adams? At least they are sailing yachts not Duch herring busses. I am racing and sailing them for years, they are tough, fast, reliable boats and locally made so parts should be no problem.
Anything made 'custom' is usually very hard to find parts for. If it breaks, well...
Anything from Adams 8's, 10's, or like the 28 which is a fully fitted out cruiser with 1.47 metre keel, or if your budget is such, 10.6, or like the 35 with shoal draught, 0.7 metre keel and daggerboard.
I could recommend them any day and they sail circles around any top hat or cavalier or such.
Joe was a tiny man so the smaller ones are lacking head room, no doubt, but Graham Radford, the ex partner of Joe is alive and well and very willing to help with plans and advise.
You won't get one for four grand, though. Those cheapies are to be aware of. Before l bought mine, - for two years - l was aquainting myself with the mooring minders on the east of Oz between Mooloolabah and Adelaide.
Have a look at my photos you'll see Adamses there.
I hope you know already what 'boat' stands for?
