Only the e-bay super-cheap tubes (because they lack the electrical contacts that let the lens communicate with the body) force you to manually adjust aperture--so it's probably better to use those with an older manual lens that still has an aperture ring on it.
The Kenko and Pro Optic tubes don't have that restriction, but cost a lot more.
Kenko only makes tubes for Nikon, Canon, and Konica-Minolta/Sony mounts, iirc. And the Pro Optic tubes do Pentax. So, you may be out of luck in terms of bargain tube sets. You may have to go with the Olympus manufactured one (no sets of variable lengths you can stack for combinations, and only
a single 25mm tube available that I can see; Amazon's charging $120 for it). A lot to pay for what's essentially a hollow plastic tube with contacts.
You could still try lens reversal, though.
