I know exactly how you feel.
I spent over £10,000 in the three years I put up with the old girl. This was spent on so called; half / cost price upgrades and repairs. Many of these should reallly have been done FOC but I guess I was a mug. Add to that the horrible devaluation: another 10K down the pan. It was an interesting experience all round.
As I have said many times: there is a huge difference between hand built and well built!
It wouldnt have been so bad if I had managed to get one full summers use out of the old girl.
