I am getting my first P3P, and i been reading about best monitor to use, and seems like Iphone brands are top of list, But having over 1200 in my setup, I just cant afford sop spend 6-700 more for the ipad mini 4 or the iphone 6. I looked at walmart, they had some small tablets that was samsung brand and was 119- 149. Will one of those work? I am sure needs to have at least 16 gb of storage. Any one have a comment ?
