I came across that set that has the DX Beta Capsule, Ultra Eye, Mebius Brace, Ultra Rings, Ultra badge, and one other that I don't recognize for about $70 (that's including shipping) from a trustworthy seller). For anyone that has it, is the asking price worth it?
For the set itself it is worth getting. Toy version of the Ultra Badge and Ace Rings are rather hard to come by since Bandai rarely releases them. The other item that you could not recognise is Ultraman Jack's Ultra Bracelet, which is technically not his henshin item since Jack do not have one.
But for $70 (in usd right?) is a little steep though... definitely much more than what I paid 3 years ago... Otherwise you may consider getting the cheaper and smaller candytoy set version that was released in 2007 that does not have Jack's Bracelet but includes Hikari's Knight Brace and Leo's Ring.
