I recommend getting one if you have interest and ability to do so. It took me a long time to get used to the latency for Blazing Lazers, but I have cleared it and Splatterhouse, Ninja Spirit, and halfway through New Adv. Island on the Mini so far, so once acclimated I think it's ok. Frankly if you aren't too accustomed to the feel of the originals it would not be as noticeable on many of the games.
I am a big TG16 fan and I'm very glad to have one.
Thank you, I will take that advice. I haven't played the originals in many years, but if they have about as much lag as the Wii VC titles, I will be fine. I don't really play shooters and I unless the lag is comical, I won't care. If I can find one after the new year, I will seek one out.
