FWIW - I messaged William regarding the bike box & trainer. We discussed a deal with shipping. William detailed all scratches, scuffs etc... and sent pics. I decided to purchase and the gear arrived today in the exact condition described. No surprises - exactly what was discussed.
Thanks again William! With regards to rainy season, I can now rotate between rollers and a trainer to break things up this year.
The other side of the story is that bloaker is very knowledgeable and experienced as both a rider and as a mechanic, and he also demonstrated to me a very high level of integrity as well. It was a real pleasure to have met him online, and I'm glad that he can use the gear.
