Graham,
I believe you said elsewhere that you're looking for one of the older Homers. I got a 2011 Homer about 6 months ago. My first Riv. It's fantastic. I put 38 mm Soma Shikoro tires on it -- may try 44s when they wear out -- and use it for my commute (with a rear rack and panniers) in Los Angeles. Take it longer (30-40 mile) rides several times a week. Have done spend a few full days in the saddle with long climbs and descents. I literally couldn't be happier or imagine anything I'd want to do that I can't.
I've had a few short spins on a friend's Hunq, double TT Sam, older Atlantis, and a zippy custom. All really wonderful. Find myself fantasizing about getting another Riv (Joe App or Atlantis) to complement the homer, maybe with fatter tires, front basket, swept back bars, etc., but every time I do so, I ask myself why, as it would mean that I would have less time on my Homer that is so comfortable and smooth. It's such a joy to ride and a true all-rounder, just as a quick as my old Raleigh Reynolds 753 road bike, when I want it to be, but far more versatile and handles better, for sure.
Good luck with our search, but if you can find one at a reasonable price, I can't imagine you'd be disappointed. Mine is all that I'd hoped it would be and more.
