I ve 6 x Asus P106-6g . I m getting 153 mh with OC on Claymore Dual for Nvidia. I m happy with these cards. Next week I ll get 6 x P106-6g also. I paid 255 USD+ tax for each one one month ago and now the prices going up. Near 300 USD
400 usd in Russia and 2 months of warranty 
line and one-month salaryFunny is, these cards usually last around 3 months or so hehe and by then there will be no warranty for you, so you stupid miners will never get your money back and in the end will be all for nothing hehe, eth at this price is a steal since difficulty is just so bloody high and in few weeks will be worse, difficulty will double and maybe triple hehe, you trolls never learn hehe, if i were you i would buy eth no stop
