Mine is nearly up to that standard just using a standard vinyl tool roll and odds and ends of tools I've collected. But if money is no object, rather nice.
I'd be really pleased, having just paid a small fortune for all the tools I'll need to repair my airhead, if I had to get the rear wheel nuts undone on my R100GS with an open ended spanner.
I reckon most will already have most of the tools they need by now, airhead ownership is unlikely to be the choice of someone new to this game. Kriega make a nice roll in which to put your tools for £20 http://www.kriega.com/tool-roll/
check out the Proxxon 36 Piece Precision Engineers Socket Set (1/4") £40 from Axminster and comes in a nice sturdy metal box. Fits in side toolbox but not under seat.
