Fz150 vs tz25

I've been stalking the site for some answers to my questions and seen a fair few posts on the tz25, tz30 and fz150.

I am probably going to go for either the tz25 or fz150 but i am still undecided. I have seen a few posts saying that the image quality for tz25 is comparable to fz150. Does anyone agree?

And also i have read alot of posts saying that users swopped there 150 for a 200 and are niw happy. Is this solely due to the superior qualiry of the 2.8lens?

I have about a week to decide which is the best to get for my hols and i keep talking myself out of one and into the other!

Any thoughts would be greatly appreciated. I prefer image qual over gps etc which is why i was considering the tz25 over the tz30.

Many thanks
