I had one original L1 and never came across any situation it wouldn't handle. I did an outdoor show at an automobile race track and everyone in the stands and on the ground could hear it plainly, yet it didn't blow the eardrums out of those seated near me.
I later added a second one (because I got a great price). I used both of them only one or twice, but never really needed the second one. Oh but WHAT A SOUND!!
I rarely do larger jobs anymore, so when the Compact came out I bought one. Loved it for anything up to maybe 60 people. I order another one. Two Compacts are easier to handle than one L1. Plus you always have a backup with you, plus you have true stereo. I played events up to 150 people without straining them at all.
I now have two HK Nanos. They are well up to any thing I do these days. It's a tossup between them and the Compacts.
You can't go wrong with the Bose gear. In the very unlikely event you need more bass (I never did for sure) you can always add another B1 unit.
As for the T1, it is MONO only and quite expensive for what it does. I found an inexpensive small mixer (Mackie, Edirol, Yamaha, Peavey--I've used them all) offers more versatility than the T1 at a lot less money.
