I want to buy an inexpensive tablet or mini-pc for the office, what should I choose?

Question

Computers

I want to put something like POS-monoblock ATOL Optima at the reception only with my CRM. Advise options? In fact, you need a minipk or tablet to cope with one tab in the browser (I want to somehow lock the device for this).
The cheaper the better) If mini-pc, then without taking into account the cost of the monitor and peripherals.
