Hi Will & Timmy boy,
Thanks for your replies....it's good to know u guys have started out with them,

sounds like a good machine to start with!!
I did worry about only being 2x2 stage vacs but i've been and got it today and good thing the guy owns a shop and has put a new vac pump in so inside looked pretty good considering its age and was still only 2x2. Was given a demonstration, the extraction/suction performance seemed good and gave a professional finish which is what im after!!
Again thanks guys for your input, it has helped allay my fears!! nice one.
Scott
