Each has their pros and cons, but overall, they're all decent. I've got
my issues with Verlinden, but Warriors, Nemrod and Jaguar are generally
very good.
Expensive is right though. It was one of the factors that led me
to start sculpting. Unfortunately, casting resin is expensive, and mold
making silicone is even more expensive (the last model making company I
worked for spent $40k on 55 gallon drums of silicone
every month!
A single drum can cost as much as $5000). And the molds don't last
forever, so more have to be made, which takes more silicone. You'll
notice occasionally that you'll find small chunks of pink or blue
rubber stuck in the parts of a resin kit. That means the mold is
starting to break down, getting brittle and losing it's releasing
characteristics which keeps the resin from sticking to the rubber. That
cost gets passed on to us at the cash register of our LHS.
Verlinden has a lot of figures, and they cover a wide range of subjects
for both 54mm and 120mm, which is nice for figure modelers because they
have a figure for whatever your interest is, but I find many of their
poses to be stiff and unlifelike. Clothes aren't always sculpted in a
realistic fashion either. Still, other figures by Verlinden are real
gems. It all depends on who sculpted the figure in question. That's
really what it boils down to with any of the manufacturers though. Who
sculpted the figure. Some sculptors are better than others, or are
better at certain aspects of sculpting the human form than others.
Assembly can be a pain in the keester, as M1 said. Casting plugs
and such, which need to be sawn off. Sometimes the molds shift or get
squished during the resin curing process and you get nasty parting
lines and often part distortion. That can't always be fixed either. The
QC process is usually pretty good in packaging and shipping, but a bad
one gets by now and then. That can happen with white metal figures too,
but it seems to be a more common occurance with resin.
