I know of a Nacra 5.8 for sale at my Club - Dee SC (on the Wirral). It would probably be within your budget, and should be as big a boat as you'd want to sail single handed, with the option to go two-up. Email me at simon dot stannard at lineone dot net for more info if you're interested. There's also a Dart 15 and Dart 18 for sale at the club - see
http://www.dee-sc.co.uk/notices.php#saleTresaith Mariners are down your way - but I'm not sure how you'd conatct them. Bala also have a For Sale page - but nothing immediately relevant right now. A few bargains crop up on eBay as well from time to time!
