I give you my candidate: The Kinhome-Class 100-Ton Merchant.
A Mongoose 2e design. The Kinhome-Class 100-Ton Merchant is designed for a pilot/astrogator and engineer team (often a couple) or the loner who can do it all. At less than half the cost of a Free Trader, it still boasts almost 3/4 of the other ship's cargo capacity when jumping a single parsec. It has a 10-ton fuel/cargo container that can be filled with fuel to allow J2 functionally in exchange for a loss of 10 tons of cargo space. If it needs to make a longer jump, there is a collapsable 20-ton fuel bladder that can enable it to reach a destination 4 parsecs away in two jumps with 26 tons of cargo.
It doesn't have enough power to use all systems at once and must cut thrust and other non-essential systems before jumping. There are no dedicated passenger cabins though the two cabins could be converted to double occupancy to allow for more crew (or as is common, children).
Everything is as basic as one could imagine. In all, it is one of the least expensive ships available in Charted Space and a bargain at the price, even with the corners that have been cut in the hull quality, drives, sensors, and power plant. One could even say that was a feature--not a bug--as that makes them very inexpensive. In fact, they are so affordable that they are even more common than the ubiquitous Free Trader and are seen all over the Imperium.
