OP: For ideas for implementing your scouting system, you might want to checkout the post and whitepaper Team 1678 has on this thread:

We used 8
Trio Stealth Pro 7' tablets for our system and they worked kind-of ok. They functioned mostly as we expected, but you get what you pay for with Android tablets under $100. They did not support Bluetooth, which was a disappointment, but they DID support USB ethernet, which we used at the Sacramento regional. I would not recommend using USB ethernet though: it seemed somewhat unreliable and a real mess with cords. At this point in time, I would recommend increasing budget a bit to $150 per tablet, and purchasing
ASUS MeMOPad HD 7s
They are pretty much just marked down previous-gen Nexus 7s, and from what I can tell the gain in quality from cheap less than $100 to $150 makes a world of difference.
At least that was my / our teams experience, maybe it will be different for you.
Good luck!
