Good cheap, root-able Android tablet.

[gregorywest501]

Looking for a good cheap tablet that I can root. I have an Acer Iconia One B1-870, but there is no root solution for it. With out being able to root, not of any use, at least to me clients.

The use of the tablets is for shop floor data lookup. The reason for root access is needed, because a couple of the inhouse appt do not work without it. The reason for 'cheap' is simple, these are on a shop floor, and often broken. So the idea is something workable, but disposable.

Don't know if this will meet your requirements but maybe think about picking up a pre-owned tablet like a Nexus 7 or 9 instead of buying a newer, cheap, knock-off model. The Nexus line was Google's flagship back in the day (before Nexus was tabled and Pixels became the new front-runner) so the build quality was quite good, the question being, is an old, quality tablet just as likely to retain longevity as a newer, cheap tablet. Also, Nexus models generally came with unlocked bootloaders, in a time when rooting wasn't officially sanctioned but relatively easy to do. Not like today where there's a concerted effort (manufacturers, carriers, and Google's Android development) against rooting.
Anyway, swappa.com is a good source for used mobile devices. An example being:

A caveat when buying an older device is the battery is probably failing or at least close to it. Tablets generally don't have user-replaceable batteries but you with a little effort you it's not a major project:

and do note that since this is a discontinued model line, even the aftermarket batteries you purchase have most likely been sitting untouched in storage for years, something that will drastically shorten the overall life of any lithium battery (they need to get at least a partial charge every few months or so, or at minimum annually.) There's little to no profit involved for battery manufacturers to support old products, so there are a lot of basically useless batteries out there in rarely used inventories.

Just how many of these tablets are you going to be distributing? Are they going to be connecting to a closed, protected WiFi network (only inside an isolated local network) or are they also going to be used for general online access to the Internet? Again, this used tablet suggestion might not be the best option depending on your needs. An older tablet running an older, unsupported version of Android won't be an issue if you're going to be using it in solely in a local network, but once you add in typical Internet access than there's a lot of security and privacy issues involved.
