I understand what you're saying and I agree to a point. Of course it's not going to be as good as a £10k+ machine, but I don't think it's as bad as you say. The newer models are build far better than the older (coupla years only) models. Either way, my only option is to try to improve in its weaknesses as much as I can and learn whilst doing it. It's fun anyway.

Take a look at this video (especially around 8minutes in). He's on my school of thought that the wiring is the main problem now, not the mechanics.
