If it's ok I'd like to add my 2 cents regarding Fast Tracks.
Firstly their customer service is fantatstic, I bought one of their jigs in May of this year but due to "Life" I didn't get a chance to have a go at building a turnout. As per Murphy I received a jig that was slightly out of spec, mine was one that got out before they realised the issue. Sent an email off Saturday night, received a reply on Sunday informing me that a replacement would be on the way mid week. I was given a store credit equal to my postage costs, I was intending to buy a few bits and pieces later on anyways so I took it as a plus, others might not. I think all up I had my new jig Wednesday week.
Secondly this is the first time I've ever attempted any kind of handlaid track, be it plain or turnout, was such a pleasing feeling to produce a smooth running turnout on my first attempt. All up construction may have been 2.5 to 3 hours I was taking my time and doing things slowly, oh yeah a new tip for my iron would have helped as well.
Yes there is an expense involved in getting setup, I dare say the development would have taken some time, effort and a few scraps of aluminium. As a "virgin" track builder I'm way impressed and in the long run I can see it saving me money and hopefully the knowledge of how a good turnout works and the skills to make "off jig" turnouts to suit a location.
I could even see how the jig for filing the frog & points alone would make life easier.
My apologies if I've gone off topic but I just wanted to share my experience.
