Monster Zero x SciFi Japan - Archive Only

I'm kinda of craving some Bandai Ultra monsters. I bought a bunch a few years ago - don't even remember the dealer - but I'd like to get more. Anyone know of places with a good selection at good prices? I'm most interested in anything from the '60s and '70s eras.

I really wish I was buying these back when you could have snagged them in abundance for $10-$12 a pop and certain figures (such as ones from Ultraman Great) were easy to come by. I've always wanted a Vakishim figure from Ultraman Ace. I know they re-sculpted that one recently. Anyone know where I could get one?

The figures I do have are:

Ultraman Ace (hard vinyl 1984 version I got in the '80s because I needed a Jet Jaguar in my collection)
Kiyla (another hard vinyl '83 figure I got because I needed a Megalon)
Original Ultraman (2000 sculpt)
Gomora (original '83 sculpt, which I'd like to update)
Baltan ('94 sculpt)
Jirass (green playset version)
Zetton (older version with basic silver and white paint job)
Antlar (have they ever updated the '83 sculpt?)
Neronga ('94 sculpt)
Telesdon (older version with bronze spray)
Dada (2004 sculpt)
Woo (2002 sculpt)
Pestar
Red King (2000 sculpt)
Bemlar ('94 sculpt)
Gomess (painted version)
and finally a full-size 8" Ultraman figure (stamped 1989 on the back) with articulated wrists and ankles. Whats the deal with this figure?

I have a tagless Rigatron figure for sale, but he's got some significant paint wear to his face.
