Fisher-Price Rainforest Jumperoo seems to be one of the better jumperoos.
In Australia (new);
$170-$230 Online (post not incl)
$200+ In-store
$230+ on Ebay
Around $80-$120 for a good example second hand.
Or $132 on Amazon U.S. I also tried Amazon U.K. but worked out over $200 (shipping was the killer).

Description
A place full of wonderful sights and sounds…the Rainforest Jumperoo brings it all down to size for little explorers! Still tons of safe jumping fun (which will activate rainforest music and lights!), but now there are toys all around the rainforest—and overhead—with a spinning seat that helps baby explore them all. This baby jumper features a bobbing elephant, swinging monkey, spinning lizard and more that baby will just “go wild” for! Baby spins drum to activate lights and music (Mom can activate for four minutes of continuous play). The baby jumper's soft spring covers keep little fingers safe and three-position height adjustment ensures a custom fit for your child. Requires 3 "AA" batteries for toy tray (not included).
I think it's time they made these for adults, possibly with the activity tray swapped out for an XBox.
