Shaun, I really think you need to have a good think about what you are already achieving, you seam to be on a constant search for something new.
like you constantly remind us :
:
you were the first to get a glide, you bought the H/M glidemaster now you want the RX
just be happy with what you've got, do you think you can clean carpets any better with these new toys?. You do a good job already, keep your money for other things.
