a couple of points.
If you come to the USA I would recommend annapolis
as a good place to start looking for a boat, lots of boats, lots of brokers and access to the Atalntic and the Carib.
Boats to look at; If you are importing back to the Eu you would be better off buying
a european built boat- much easier and they will also have met the RCD. I have helped a few of my friends by boats here so have been through this at least three times. I presume you know all the Europeand manufacturers, all of them are available used here. in your price range you will find currently a Dufour
31, Arpege, Moody 31, Camper nic 33, Elizabethan 30, and a couople of westerly's
US built boats, you will pay less, or be able to go up in size,
I would recommend looking at the CAL
range the 35 is a pretty boat, currently there is one for 29K,
and Irwin- at around 30K you will find something in the 34 foot range maybe a 36/ 37, the Irwin
in particular can be a fine buy.
There is currentl a very nice Morgan Out Island
37 here for $32K, a nice cruising boat.
There maybe more, if you are interested PM me
