There's not alot over here the cost and also the 'electric mark' which has to be given have all been a problem, Oreck orbitors seem to be the order of the day but I never liked mine it just shook everywhere, Solutions Uk did bring over the Challenger and also did make their own version which looks like an Orbot but weighs a ton! but a good friend of mine has one and he loves it.
If you are planning to bring any over here please let me know.

PS used the smallest Argonaut but that was too light and quite uncontrollable would have like to try a bigger model, a company called Dry Fusion did have a vibrating plate which was for stair which I believe was of Italian make.
