Be aware of Mt. SAC's incredibly high fail rate. I know some really smart guys who attended and failed out...twice. It's incredibly difficult with little assistance (from what I've been told). You have to be a self-learner. They hold a very high bar which I appreciate, but aren't what I would call good educators (which I dislike). I've been told test answers require memorization rather than understanding.
From what I've been told, the key is to really prepare yourself. Someone told me out of a class of 20 or 30, there were single digits left at the end. It's cheap, though, as you just pay community college tuition.
If you can do it, it seems like you're learn all sorts of stuff. A LOT of specifics. You'll definitely know what you're talking about when you explain any topic you've learned to others.
Definitely better than PTI, though! Don't know what it's like compared to UCLA. I know UCLA does have to cater to FD's to keep spots filled (and thus not go under), so while the education might be top notch (some really educated people there with great experience), you might not be pushed as hard as could be....
Give and takes.
I recommend you call them all up and sit in for a day. Meet with their directors and such.
