I got my S5100 a few months ago. All I bought for it are 8 NiMh batteries w/charger and a 256mb card. Haven't used it for models much since my older 2mp Olympus works just fine for that purpose. I want to get the telephoto add-on before the kids' soccer season starts although the 10x zoom is pretty good already.
Here's one of the few shots I took when messing around with the Fuji (resized, of course).
The competing Canon S1 IS at least zooms in a portion of the scene when manual focusing so you can tell if you're really focused or not, the Fuji just takes a little more squinting. Still, the manual focus is a big plus. Nothing ticks me off more when taking macro pictures than listening to the autofocus go "zzzt zzt zzzt zzzt" until it tells you it can't focus, which is what my other film SLR does. Getting a manual focus lens for my SLR would cost more than the 5100.
