There are currently two similar threads, the other being: http://pioneerdj.zendesk.com/entries/27306616-Is-the-XDJ-R1-ripe-for-the-picking-
Qualifier: Neither product fits my needs, so I have only owned both models on a temporary basis (retailer return policy.) My daily rig consists of a pair of 2000 mk1 and a DJM900.
I would say that the R1 with current firmware is still not ready for prime time paid gigs. Aero firmware appears reasonably solid, but lacks a number of features and is clearly targeting a different market. With the R1 and this current (v7) firmware, I have ceased the 'buy it - try it' as I have with each firmware release as a distraction of time until I see a consensus on the forums that one of the future releases is solid.
