Good news! Please get a Moto z, it is much thinner and has blazing fast qualcomm 820 and better screen. I am willing to support you with 100 bucks via paypal if you purchase whatever moto z series device you can get. As you have seen the price drop to 249€ of moto z here in germany, i guess it will be possible to negotiate down to that pricelevel at many resellers also in your area soon.
Perhaps I can lend you a spare Moto Z or Z play for development, after our internal testing. Not 100% sure at the moment as product still under development and software needs to be tested... If it's not too late.
