Mine would be the old system, but as it stands I don't have one but I have a heavily modded top loader which behaves like one instead. If I ever came across an unabused new-ish looking old action set (lacks zapper and other foo foo) with 2 solid non bitten/dinged up controllers I'd jump at it if it wasn't an ebay/ebay plus gouge price. I see them now and again a few times a year but they're loose and beat to hell. I'd take a pristine one, boil the pins back to factory or better, snip that security chip, and sell the top loader with the controller it came with and keep my 2 spares as they're comfy.
