Also Keith Wiseman of Wiseman model service offers a On3/30 kit of the American Hoist & Derrick ditcher and also The AH&D log loader.These are beautiful kits and if my memory serves me they are around the same price range.I have built one around ten years ago and it is truly a foreground model and if you really want something nice he has the Marion ditcher in On3/30. www.locopainter.com
