Inexpensive devices to code Bolts

I am using Bolts with an afterschool club. We were using old Asus tablets to connect and had many problems, the tablets kept dropping the connection to the Spheros.
I am looking for other devices to use with the Spheros. They would only be needed for the Spheros. Ipads are too expensive, any experience/thoughts about using Amazon Fire Tablets (With Prime Day coming up I am tempted to buy)? I am open to any suggestions.
