Well, I bought a Trance X frame and have built up the spec over a couple of months. Probably not as good value as the base model from a shop in the sale. However, I have been able to spec stuff that while still basic, is at least my choice (so coil sektor dual position forks v tora, deore drive train and brakes, except for XT rear mech, Mavic Crossride wheels v own brand Giant). While not being a pimp build, at least I could go for stuff that was all ok quality wise.
Down sides are not such an easy warranty deal if you have a problem and some of the total cost of build has been hidden by my creative accounting, so some of the value is in my head!
