I'm looking for a pump upgrade to go stage 2+ and was seriously considering this when I do it but if a full APR pump is £500 instead of this at £350-400 for ineternals I think I might get the full APR pump.

Anyone any opinions on this before I take the plunge?

Thanks Allan
 
I think I will give them a phone mate. £500 plus your own pump from apr isnt that bad though
