Well I've pondered on this all night. It was cloudy so I went to bed early. I've made my decision, thanks to your advice. I'll buy a second hand one for the quick solution. And I'll slowly build one as a long, long, long term project. Should have it finished in about 5 years the amount of time I have off. It will be slow but I imagine it will be quite a rewarding achievement. Good luck to me.
