Free time is something I don't have a lot of: I own several small operating businesses so although my creative juices are flowing, I doubt I would ever get it done. On Track seems to offer both a beautiful scale selection that can be customized and is affordable. I am happy to pay a reasonable price for that level of craftsmanship as I would like to support someone's talent, time and expertise.
I wish more of the kits that are handmade were a little less (building wise); a few hundred is doable, but when it hits $1000 I get a little gassed at the price. The Slayville sawmill comes to mind.
