Hi Craig
You will gets lots of different opinions as to which is the best machine to get, so here's my pennies worth.
I have just purchased an Airflex Pro Mini from Cleansmart in Nottingham. It's a lovely machine, small enough to be very portable (taking it up and down stairs is a doddle) yet powerful enough for domestic and commercial use.
Matt provides an excellent service and lots of advice on which machine is best for you. Make sure you get some training though, which is way more important than anything else.
Best of luck.
