Band saw is a femi from these guys:
Cracking saw, very precise cuts.
I just used galv weld spray on the welds, so far the furniture is holding up fine looking like the day I made it. I ran out of galv weld on the little table and risked it. There is significant rust coming through on a couple of the welds already. If I was doing it again a would probably have something like this galvanised.
As for total cost, I would say off the top of my head about £400 all in with cushions and decking.
