The TRT seems to have the best timer of the options available.
If you have multiple inputs, you can run more than one box too.
I run one into L-1 and one into F-1 on the vcrs and I could run one or two into analog as well.
I can set the vcr to record from L-1 and F-1 and then when the vcr is set, the TV defaults to the analog feed through the vcr, in my case the F-1 box.
That's two choices without even setting a box timer, from S-video too.
I may have some extra timer boxes available if you need one.
