To be fair: for the price of these two you would not even get one Xjoy 37. There must be a difference somewhere.
But it's good to hear these small dpv's offer some serious performance. Had my doubts seeing the specs from Suex.
it doesn't have any luxurious futures but i think its the best dpv you can get for this price (in Europe). The xjoy is nicer, but like you said the xjoy 37 costs more then 2 times the price of 1 vr.
I think the specs are pretty good actually, compared to the older models xjoy 14/37.
