I figure the mid-grade $60-75 pumps would pay for themselves after a few years, even if I just use it for 1 in 3 OCIs. But before I pay that much, I want to confirm it'll work by trying something cheaper and easily returnable if it doesn't.
I have a few factors to my advantage in that, even though the dipstick curves, it doesn't look like anything a flexible hose can't mimic (though I won't know for sure until I've tried it); also this driveway has a nice slope, so with the car oriented in the right direction I might be able to get more out than if it were level.

On the plus side, you will have nice pump for filling transmissions and differentials when you are done.
Like others have said in various ways, oil temperature is a big deal. Definitely don't use vinyl tubing. You should be able to find something more temperature resistant in a hardware of car parts store.
If you have your oil as warm as your tubing and pump can tolerate, it will make your work easier.
