As much as I'd like to agree with your comment about investment in trains and the cost -- some of us are on a very tight budget and £300+ for a controller is way too much. Most of my traction is sourced via ebay and fettled if its not 100% ok, as is pointwork. investment in time, for me, is a cheaper option. I know everybody has their strengths in one field or another I just prefer to refurb what I can or build from scratch if its feasable for my limited talents.
