Hi AndyHave been following a lot of the 'Luney'
Layouts for some time but not posted on any of them before.
As regards the cost of track - building your own copperclad turnouts, even with the new price increases from C&L works out at less than half that of Peco (unless you are building something large - but much better looking and running).
If you can use a soldering iron and a file it's really not that hard. And it doesn't really take that long (I think that is a large part of the cost from Marcway: they have to pay someone to build them).
My first turnout took around 4 1/2 hours - now, with a bit of practice, and some simple homemade wooden jigs, and having learned what tools (which you probably already have) I can build one in about 2 hours.
By the time your shed is up you could have built a lot of the track!
