Solvents?

And type of manual scrapers?

grinders or some other abrasive?

I can't damage the sub-floor (concrete) underneath.

A five foot solid steel wrecking bar with a chisel point will do just
fine and you can pick one up for probably less than 20 bucks.

They weigh about 50 pounds or so, all that force is concentrated to
the tip, when you slide it on the underlayment the majority of the
tiles will simply pop off. The ones that dont, hit em with the bar
from the top and pulverize them.

There is no underlayment. It's a solid concrete pad. There is no basement
to this part of the house. With a point I'll chip the concrete

That said everyone says use the power tool with the scraper. I guess it's
worth $100 by the sounds of it.

You are going to chip and ding the concrete no matter what. Small
scratches, pops, and dings will not prevent installing the next
floor. The power scraper will gouge more than the pinch bar. You
can use a brick set (wide cold chisel), a heavy hammer, and a face
shield.
