I am currently camera-less, and I wouldn't want to post phone pics of something that clearly you want in detail!!
To be fair, it's under £200 for a custom build frame delivered to your door. The quality is more than good enough for that price point. From what I've seen, the welds get better and better. Mine are more than good enough.
DO NOT under any circumstances get the built in tensioners that he offers. I had to grind mine off after 2 minutes because they quite simply aren't strong enough. If you want horizontal drop outs, get snail cams, I had them on mine and it's fit and forget.
So long as you are very clear with him about what you want, he will sort you out. IMO the best way is to choose some geo, and keep the frame SIMPLE. The simpler it is, the less chance there will be of you being disappointed when it arrives.
Bottom line, love mine, would buy another.
