Here is more info on various handheld "immersion" blenders at
epinions.com:

I have an older model stick blender with a metal shaft, but I don't see
a brand name anywhere on it... it's fairly heavy, brown on the cord
end, cream on the bottom, and came with some bowl-like attachments for
doing nuts and things (which I never used). At the time I think it
cost about $20-25 ....it doesn't have a full "guard" all the way around
the blade, just a few metal "fence" areas.
As for use, I LOVE mine. It doesn't feel plastic-y like some I've seen
with the really cheap ones, and it's been plenty strong (...enough to
pulverize anything I've ever tried), but haven't owned another one to
compare actual use. Hope the darn thing lives forever.
Nowadays, I use it primarily for two things (frequently):
....pulverizing just parts of a soup or a stew to thicken them, or a
whole soup ...for example, when I fix bean soup or beef stew, I stick
the whole wand into *one side* of the pot right on the stove and whirr
away --I used to remove part of the food and blend in a separate
container but found I didn't need to do that, and didn't want the extra
hassle. That leaves most of the beans or carrots, beef, etc., intact,
but purees about 1/3 of it (I then stir everything back together).
....making small smoothies as bedtime snack from homemade yogurt
Since I add frozen fruit (cut into small chunks) along with some sugar
to the yogurt, sticking the wand right into the paper coffee cup which
is holding the other ingredients works out great.
Checking epinions again, looks like some of the differences between the
blenders mostly have to do with number of attachments, number of
speeds, and motor power.
For example, some of the slightly more expensive ones come with up to 9
speeds or so, as opposed to the 2 speeds most have... some of the
motors are a bit stronger than others, but most are strong enough to do
most jobs (except perhaps to crush ice --one unit which was supposed to
crush ice was disliked by its owner though because after awhile,
crushing ice broke the plastic of some part which messed up the whole
blender).
There was one important difference, with the Hamilton Beach I think...
its reviewer said it had too short a guard around the blades and
scratched up her pots --definitely not good!
