I've got the Porter Cable 18v set, impact driver, 1/2" drill, jigsaw, 6.5" circular saw, light, two batteries, and charger. You can upgrade to li-ion batteries and charger...the tools will use either. I bought it in stages, one set with drill and impact...etc. I didn't expect it to last. I've had most of the tools now for a least a year...no problems.
