P6 training in UK? Would you help please?

I would like to do some training in P6 (self funded). Have been in touch with some Primavera certified training providers in UK (I live in London).
Most them offer 2days training (106P Primavera P6 Advanced – Projects, 106R Primavera P6 Advanced – Resource Management) at the cost of above £600 each course. I have the basics already.
Do you know a best one in terms of (quality/price)? Which one you recommend?
When I asked, one of them said our trainers have an experience up to 4 years in training. My fear is that those trainers have IT skills and may not give enough emphasis to project planning in practice! The course becomes simply how to use the software rather than a project planning course. What would be your experience? Can please help with your views?
Also, I would like to be with you project planners, especially those in London/UK
