*giggles, to be more specific, you pay $30 to soe for the transfer. Thats where the cost comes in to play. You make an entertainer, macro grind to level 90 *mustafar to learn the instrument song from npc in cantina at lowish level, then can learn the dance from other npc same spot. This gets you to 90 in 1 day or 2. Once you are level 90 you pay swg/soe $30 for the transfer from one server to another, then when you log in, go to change profession and the usual reset of level doesn't happen..
You should be able to search the net for details on how-to's with the macros etc and where to go in mustafar.. the cantina
