You can read all of e036 as it stands, but add in the following paragraphs to the end:
"Other options exist if you already own a starship. You may purchase another Antelope ship on credit and can trade in your old Antelope. Assuming you have paid off the loan on the first ship, that is. This option is not available if you owe anything on the old ship. If this ship is paid off, you will receive 60,000 credit against the principal and the interest payment will be reduced.
"You may also purchase a different class of ship under the same terms.
"Ships obtained from e001 have all of the items listed for an Antelope class, meaning you could be missing guns, hoppers and the like.
"If you wish, you may purchase anyone of these ships outright. Please see the table below for all options.
"When trading in an old ship, you may transfer any gear or cargo from one ship to another, however, you may not remove the ship's guns, boats, boat guns, hypercharges, or permanently installed stasis units in the pilot's area. Items in the cargo hold count as cargo not equipment. If you are missing equipment, the ship is not sale-able and you will have to purchase these items either before going to the dealer (a die roll) or purchase them at the dealer's price.
"You may not roll against Cunning to negotiate the price of these ships, nor may you use ANY another mechanic such as psionics, drugs or pheromones to alter the prices. All attempts to do so will make you wanted in this system."
Players may wish a refresh on the alernate Hoppers:
Orbiter, e034. 1800 secs. base price. e035 is 2400 secs.
Fast Boat, e034. 1000 secs. base price. e035 is 1500 secs.
Interceptor, e034. 2500 secs. base price. e035 is 5000 secs.
Remenber, the Orbiter is larger than most hoppers. Their full description is here.
