Love you too Dave :S
All I was trying to say was that when you buy a Leeson you are paying £400 to have a frame specially built for you, with the exact geometry you want, by some guy who knows his stuff. Which is nicer than getting a £25 aluminium frame for £500. I just can't help thinking people are being ripped off paying through the nose like that. However, if there was an aluminium frame with the exact geometry I wanted, with good strength, for less money, I would be right there (Cue Onza :) ). I don't really have a preference between steel and aluminium frames (I'm definitely not convinced by the "Steel is reel" thing), all I know is that my bike is exactly what I want and is awsome fun to ride. To answer your question: No, my Koxx never failed me, but the Leeson is better.
I'm not comparing a custom steel frame to something reasonaly priced a T-Rex, but XTP/Gu frames look so overpriced.
