Real McCoy's has long been the gold standard of J-100s, very high quality and Shinki Horsehide. If you went stitch by stitch and also compared the Shinki to other leathers, then most would probably agree that it's a higher quality. On the other hand, if you ordered an Aero in their Vincenza leather, then it becomes a debate as to whether the difference is worth the $. I don't think the collar on the Simmons Bilt looks good, at all...
Diamond Dave is a relative newcomer who is mentored by John Chapman of Goodwear, and he makes a very very attractively priced J-100 replica. You can search around, as he has reviews running from glowing to disappointment. I own one that came out great, but I've also owned an Aero Board Racer that was very top notch. It's worth looking through a lot of pictures, as patterns do differ between the companies.
Thanks for your reply.
This will be my first leather jacket. At the moment I tend towards the Buco jacket. It might be the most expensive option, but I can at least visit the Real McCoy store in London and try it on before I buy it.
Diamond Dave seems to be interesting, but I prefer Areo. The Board racer in Vincenza leather looks really good. However, here in the UK, purchasing an Aero jacket seems to be overly complicated. They have no retailers and one has to order from their website, which is not really user friendly, at least not for a novice. I could just order a stock jacket in my usual size, which might not fit properly. Then I would have to send it back and order an other one, hoping that it will be better.
