In response to your e-mail, it looks like you've got a good handle on what
you need.  To answer your questions.  The *Lego* starter kit has the 
interface box  (this is the connector or intermediary between the
motors on the rover and the computer.)serial cable (this is what connects the interface
box to the computer.
Make sure you designate PC when you order.  I have cables for
both Mac and PC, because we started with Lego Dacta on our
Macs just for the programming part of it before we ever heard of
Red Rover)software (this is the Lego Dacta software only
which allows you to practice with the programming, a good
experience.  When you actually do Red Rover, you do not use Lego
programming, however.  Planetary Society has its own
software for that (included in their kit)kit #9702 (one kit included.  
As I mentioned, you need an additional motor for each rover, some extra gears, large,
and possibly even some extra regular red lego pieces.  I asked
all my kids to see if their families wanted to donate any old
lego kits, parts, etc. I put all these in an extra bin for everyone
to pick from.) curriculum kit (included - this is for specifically
Lego Dacta building projects and programming - does not include
instructions for the rover, but is good practice to build one
of the projects and practice programming)

Sounds like you might need one more motor (for the one in your starter kit),
so you have 2 for each kit.  Also, I plan to use big balloon tires this year
instead of the smaller tires offered by Lego Dacta.  I am getting the catalog
on that shortly from the regular Lego division and will let you know how to
order them.  You might want to save out $100 or so for extra parts like
gears, tires, and unexpected items.  Also, don't forget you will need some
funds for building the Mars site.  You might be able to use art supplies your
school currently has, or perhaps some creative parents can help with that.  I
purchased most of our supplies for the site and I believe it cost us about

One more the early stages of your students projects, you will be
doing alot of "testing" of the rovers by hooking them up to the interface box
(there are special wires in the kit which hook up from the motors to the
interface box).  With one interface box, you will be needing to work out a
good sharing schedule during building time.  We had 3 interface boxes
because, like I mentioned, we were doing Lego Dacta projects before we did
Red Rover. However, these boxes are $227, so that puts a crimp on many
budgets.  In the end, you only need the one for Red Rover, but I just thought
I would mention it.

Anyway, bottom line is you sound like you are basically all set with your
list.  Just some extra $ for the tires, gears, etc. and maybe for the Mars
site art supplies.  Oh, there is a 6% shipping charge for regular shipping
from Lego, 10% for 2nd day air, but not tax unless you are in Connecticut.
 Regular shipping is very slow, sometimes 2-3 weeks - might want to keep that
in mind.

Please feel free to ask me any more questions.  I'm happy to help with the
next step after you get your supplies.  Theresa Hall
