If you're on a strict budget and don't need to run much on a tablet, (scouting software isn't processor-heavy) I recommend getting a set from
Alibaba There are some models that require a minimum of 1 piece, 5 pieces, or 10 pieces to order. The prices will range from around 20-60 bucks a tablet. The hardware in these off-brand models are pretty much the same as those of name brand models and they run Android. My team uses off-brand tablets and they work perfectly for scouting. I even use an off-brand tablet myself for personal use.
The same site also sells tablet cases.
No need to wait for Black Friday or Cyber Monday! You'd get a better deal from Alibaba or other wholesale websites anyway year round.
