I'm shopping around for a delay and I've narrowed my choices down to a TC Flashback or Flashback2 (or a used SA Nemesis if I come across a used one I can afford). I'm more likely to go with a new Flashback and all things being equal, I'd go for the Flashback2. However, I can get a new Flashback for $99, while the Flashback2 is $169. To those who are familiar with both, in your opinion, are the new features useful enough to be worth the extra $70? I know that to a lot of people, $70 isn't that big of a deal, but I need to stretch my dollars as far as I can. I know there are a lot of people with recommendations other than the Flashback or Nemesis, but I'm intrigued with the parameter editing capabilities of both and the price range of the Flashbacks.
