I ordered the JMI shown on this page for the 2.7". I checked with them to make sure it would fit my TOA130 and they confirmed it.

Regarding the collimation, I used Paul's Pico Star and it looked spot on, so I can hopefully put that one to rest. He knows a lot more about scopes than I, and in his opinion the collimation is spot on according to the Pico Star test. I sure was not looking forward to the idea of having to send it all the way back to Japan. I got one quote of just under $400 one way, mind you insurance was a kicker.
