Migear, Holysmoke Idisco, Ion Party Rockers & Block Party Machine

I have been eyeing up a ion block party live or party rocker live as said made by ion who are well known overseas and have made some good items based in usa.
This item has disco ball light that fills room and also gives out not bad sound so i have read.
But it comes at a price ion brand depending what model of two above block party being more portable.
I find one guy who sells these in oz but older models and more expensive and has no interest in getting the above models in.
Its a shame as plenty of reviews online and vids to watch but i have issues in getting it sent over here,but from usa has no issues sending to here but they use 110v where as other places can use 240v uk,euro,oz etc.
I have since found that companies in oz are trying to copy ion with there product and im sure may not be as good its the migear party rocker and holysmoke idisco.
Both of which i can get at a sweet price but my issues are not knowing these companies as well as ion,no vids showing these in action and no reviews.its good to have an idea of what your buying or what others have thought do any of you guys own any of these migear or holysmoke idisco? Or even the ion? Im interested to know about the first two as dont know much about these guys where as ion i know but hard to get here in oz or pay a price for.
