Well if money is no real issue, I don't see why you wouldn't get the Model 2.
It's:
1. Smaller and more portable.
2. A greater "spread of sound" due to the angled speaker drivers.
3. Works well with the T1 Tone Engine ** (Mixing desk) in case you need some flexibility in the future - we all need that sooner or later.
**To be fair, the T1 works just as well with the Model 1.
Possibly reason # 1 is the most important overall, I'm not exactly sure of your current gigging situation.
