I am going to have to take a real plunge on this one and go for the FZ150 but despite every encouragement I read on here I still remain nervous.
That's understandable.
Kevin C is "shooting straight" with you. Do not underestimate the "I chose to purchase and now use one - therefore it must be good/better than X" factors that may (in some cases) be at play on this thread.
Why not keep the D3100 around until you are convinced that it has (for your intended functional purposes) been adequately "superceded" by the FZ150 ?
A look at the (as I perceive it) "image-quality" shows that while the FZ150 is (in all cases) clearly a better choice than a FZ100, it is (still, in all cases shown) easily "blown away" by the D3100 - and (even) appears (to me) to be meaningfully challenged by your LX3. Have a look at these comparison of what high spatial-frequency (finely-detailed) subject matter looks like through the "eyes" of these various camera models:

Is the D3100 really that much larger and heavier to "lug around" than a FZ150? Neither one of these camera models are "pocket-able" in any sense of the word.
I submit that it is the
lens-systems themselves that are the dominant (size/weight/cost) issue here. Do not lose sight of what one gives up in exchange for a (smaller/lighter/cheaper) lens-system ...
If you feel that the lighting conditions will most frequently require a (mere) ISO Sensitivity Gain of 100 or 200, and that your subject-matter will not be in-motion, then (it seems to me) that the FZ150 may have chance of satisfying. If not, perhaps you would be wise not to part with your D3100 until you are satisfied that the FZ150 really can "fill your bill" ?
Ye, it is true that
Gary S ,
LTZ470 , and
Kevin C (in certain conditions, often using tripod-stabilization, and with mild to exotic post-processing applied) have yielded some impressive results from the FZ150. In high light levels, a few other posters have demonstrated some pleasing results.
But only
you will know what all of that (and all of the "sizzle" bubbling-away) really adds up to (for your applications, and through your own set of eyes).
The more wildly optimistic testimonials become, the closer one (quite rightly) ought to scrutinize ...
For those who may (as in the past) took umbrage to my thoughts, please answer my words with actual
FZ150 images with full EXIF (or at least ISO, F-Number, Shutter Speed, and user-control setting information provided). Words and emotional gesticulations have a way of only going "so far"
