When i bought my house about 7 years ago i got the rigid set, and the reason why is that the tools and the batteries had a lifetime guarantee. Now i don't know if that's still the deal, or if they even have a grease gun or other tools you are looking for, but the set i got is awesome. We run dewalt at work, I'll take the rigid set any day. If i remember right they have adapter deals for the batteries now (so different barrettes can power different brand tools), so getting a rigid set for the lifetime batteries and whatever same voltage tools from whoever might be an option.
