just type: estes rocket in the "What are you looking for" box. You can check "Completed items" if you want to research pricing.
That yielded four pages of stuff.
You can also type
centuri rocket
Aerotech rocket
If you leave "rocket" out you may find more, but will have to sift through other stuff as well.
In case anybody is interested in old kits I know the locations of the following:
2 saturn v's
2 Honest Jonn's
5 Explorer Aquarius
1 Estes "High impulse" launch pad
1 Estes "High impulse" pad and controller
All are OOP and at regular retail (hobby store) prices.
Sorry, I grabbed the Atlas.
