The operative phrase here is "if one has patience".

As I said, they typically go for £80-£100, but not always. I got my TI-92+ for £50 and my TI-89 and 89 Titanium for £60 each and considered it a bargain. I also got a TI-84 Plus C Silver Edition for under £40, which really was a bargain. However, I paid £90 for the Voyage 200 and seriously considered a different one at £150 at the time.

I got a Ti89 as a door prize last year at the HHC2017. But didn't succeed to make myself familiar with it.
