OK, so treated my baby to a big workshop for over the winter for some polishing & suchlike.
Got one from Treetops in Cannock, they are on Ebay

Link should take you to their shop, all I can say is what a top bloke.
Basically you can have whatever size you want, really good build quality, they deliver all over the country & build it for you on your hardatanding as well, all inclusive in the price.
2 guys came this morning, arrived at 8am, gone by 9.10am, took them 10 mins to drink a cuppa before they went.
Really really nice couple of blokes, really friendly.
I am chuffed, this company well recommended.
Now for some electrics & heating, I may be moving to the shed!!!!
