Oh, somehow I thought you were buying it new.
Remember that the more complicated something is, the more likely something will go wrong.
As far as my experience, unless I was working on digital electronics (and then a logic analyzer is better) two channels on a scope is enough. Two channels allows you to compare the timing of two signals, you really don't do that very often on a TV. On some scopes the second channel is used for the X axis when displaying in the X-Y mode. For TV use a bandwidth in the 5 to 50 MHz is fine.
