Price battle was fought, Ryobi is the winner..
Ok, just got back from Lowes and Home Depot. I passed on the Porter Cable offering at Lowe's and went for Ryobi 18v lithium 4 piece set at HD. My wife was slighty annoying on why I had to have the lithium.. That was a draining 2hr conversation. We get to HD and the only set they have had signs of being opened. My wife has a thing about that, so she made some remarks about not buying one there. The manager was helping us at that point and offered 10% off since the box had been opened. He then offered to let us inspect the kit before purchasing it. The drill showed a few scratches but other than that all looked new. He noted the scratches on the drill and sent us to the counter. He gave us a big discount on the kit. Retail price is $259, we paid $185 including a 2yr extended warranty through HD after the 2yr manufacturers warranty is up.
I'm happy with that. Saved some money, and got an extended warranty for way less than retail.
