Have you ever played an MTD before, or are you just testing the waters? What are you playing now?
Threads like this are indeed GAS inducing. For a time, I was actually following this thread as well as the Club Sadowsky and Alleva-Coppolo threads (until my doctor advised me to stop

). Never owned an AC; no Sadowsky I've ever owned has stuck around for very long. Those are great basses, but MTDs are my happy place. Whether or not it's your happy place depends on what you're after.
I've owned enough MTDs X35's to know that the playability and feel is exactly what I'm after. Tone-wise, I lean toward the Super pickups and pre, although the traditional pickups and pre are really nice too. (In fact, I just picked up a used 434 with the traditional electronics, and I'm really looking forward to having that sound available to me again.)
There's a Super 5 in the Classifieds with sound-clips that's worth checking out.
