Hey pal, first of all, welcome to the forum. There's a post limit here before you can list items, and rules on selling which you can find in classifieds section.
The IR3 is worth around 30-40 in working order I suspect.
Ion around 30/40 again
Spyders are both probably a tenners worth, and I don't think you'll get much interest.
You have a sterling (I think) and an ACI Maverick pump, I've no idea what they're worth.
