Which Tablet to buy?

What brand/model of tablet would people recommend?
I'm an iPad user, so don't know anything about android. Wanting to buy 5 of them and can't afford to get iPads.
TIA

Also, what size screens are people using? Our keyboard player would like to have 2 pages of music on the screen at the same time.
