If you are in the market for a new system, I think the first question you need to ask yourself is what your budget is. The best value for money is still Purefreedom. If you don't mind spending a bit more money, the new Gardiner Pole Systems Super-Zero Crash Tested Systems should be on sale in the very near future. Might be worth waiting for. It's supposedly not catered for the same price category as Purefreedom, but should still be better and cheaper (hopefully) then Ionics etc. Maybe Alex can shed more light on that.
