A quick tip to gain cash. Find a high tech world with a low law level and buy as many PGMP'S as possible, although there may only be one initially. Then go to a lower tech, higher law level world and sell the merchandise. The ideal planets are: LLUN/EFATE (When using the trader character on the disk you can purchase a PGMP for 130500 credits) and STUR/EFATE (Where not only is there a PGMP lying on the floor NESAR the gun shop, but they can be sold for 244500 credits). In no time at all and with a little cost (because you are staying within the system) you will gain riches untold!
