Immigration requires that my Thai degree (issued at a Thai university in Thailand) is legalized before they will convert my Visa on arrival into a Non-b. I have been told I need to legalize a certified copy; others claim the original needs to be legalized.

Any ideas?

The Department of Consular Affairs of the MFA legalizes documents issued here.

There is a flow charts that have contact info for legalization section. I suggest you contact them about having you degree legalized.
