Thanks for the idea
I have been using this one since early 2002 and did not know that. I sent the folks who are now selling the unit as the ETi-1 a message and while they will not sell parts, they did offer to sell me an "out of warranty" unit. Have not asked about a price yet.
I own a Sony 505 and a REB 1100 as well. It is just that nothing beats the 1200 for reading in the dark.....
I'll give your suggestion a try tonight.
