Know that patch of water very well!
Again as has been said.... think you may struggle on that budget - but needs must as they say
Give Dominic at North Atlantic Rib Marine a ring in Derry - he had on brokerage a Ribcraft 6.5 with a 150 Johnson on the back - that has been for sale for quite a while maybe a deal could be done. He will also know if any bargains going in/around your locality.
Every now and then a decent boat turns up on Done Deal but am sure you watching there anyways.
