The ZX the fellow I know is selling is newer than I thought, but looks a good bike, but way over what your budgeting for.
Don't blame you for wanting a break from the roads. Was reading earlier about average speed camera's getting installed down you private race tracks around Tyndrum/Crianlarich.
Personally, I'd go with a van. I would be lost without mine. Bought it primarily for crossers, over 10 years ago. No crossers in the shed these days, but I wouldn't be without a van these days. I very rarely use my cars. Only drive my XC60 when going away on mainland trips with the mrs, and the other cars are just toys, same as the bikes. Just reaised earlier I've got a different vehicle on the road for each day of the week.
