I see only Pentium Gold based Microsoft tablets under $500. I guess that cheaper than $700-800 will be hard to find, and you may faster get a 2 in 1 laptop with better specs.
You can get something like this for any tablet
Or a compact keyboard and small Bluetooth mouse. Personally, I hate touchpads, and using the touch screens is still weird for work.
