any idears

Carefull saying something like that round here .  The contender is a fundamentally well designed boat, whereas a lot of the newer laser, RS, topper ones are not, modern does not nessassarily mean better.  As far as single handers go, the cheapest MPS on sale second hand at the moment is around £5500 i think, 700s are going for about your budget, but the class is busy dying on its arse.  The contender has a huge and highly competative fleet both here and internationally.  You could buy a reasonable moth and put a foil kit on it for your budget I think, and you would at least be garenteed to have the coolest boat at your club.  Having said that yo must also consider what boats you will be racing against day in day out. 

i like contenders but i would like a more moden boat

I know what some of us are going to say! (I've got names...)
 For your kind of money, with your weight, GET A CONTENDER !!!

Never believe some forum contributors who pretend Contenders can only be sailed by gorillas. It's a lovely boat, even with - and especially because - of its drawbacks.
- Keeps you fit: pull it up the slipway.
- Keeps you supple: duck under the boom to tack.

I'm sure Matt or Contender443 will have plenty of other good reasons to bring forward.
