Me too. Enter it in the MTO Group Build Keith. That gives you four months in which to build and paint it, and you can ask questions along the way to help, possibly even have some cash to spend on decals by the time you need them.
By taking your time, with care and patience, you'll get a much better model, and this kit deserves it. The standard of the finished model should be much higher, and there will be nothing to be ashamed about - it's the taking part as much as anything elses that is the whole idea of the GB's.
If you feel the need to rush to finish it, then you can always start on another kit, to 'satisfy the urge'! As Wojtek has said, modelling is not a race and, although there is often the urge to want to get a kit finished, by taking your time, and paying attention to detail, your skills will improve enormously, and you'll get a lot more value for money from each kit you build. It will mean that, for, say £15, you could get a month or more of entertainment and pleasure building and painting one kit, rather than rushing it, and spending another £30 on two more kits to 'bash out' in a week each. This will allow your budget for modelling to be much more effective, as a years worth of modelling will only cost you about a quarter of what it's costing now. That's the equivalent of an airbrush, a compressor, some tools, paints etc etc.
