I have 3 Tek 2445 scopes and one Tek 2430A scope. While idly bumming around eBay, I noticed that it seemed to me the 2445s were less common and on average more expensive than the 2430As. Seeing as how the 2430A is a DSO and the 2445 is analog I would have expected the opposite. Am I wrong in this thinking or am I missing something?
