The CT-26 was used in a few different Toyota vehicles including the MR2, Supra and Land Cruiser... The first one didn't look like a MKIII waste gate actuator to me to begin with and that was mentioned by another member in your thread.
The second one does look like a MKIII actuator, but you really don't know from just looks. I don't know of anyone who sell; Toyota doesn't sells OEM replacements. I know of venders who sell high end actuators that work with it with a custom adapter plate, but they generally run over $150... I think closer to $200.
Addendum to what I PM'd to you:
Here, I found you a relatively inexpensive universal... you just need to figure out how the heck to mount it:

) and have a mounting plate fabricated.
If your budget is tight, you only need a stock actuator and if you want a brand new actuator, I'd buy the one you found first and have it either modified or get an adapter plate built and the actuator arm modified... it'll be cheaper than buying the Turbonetics AND getting a plate built for it.
