The changes they made awhile back really cut down on gil seller tells all over, I think. I'm on Cactuar and like it a lot. Buuuut, I think with all the current and upcoming cross server features, if I were looking to transfer, I'd go to one of the low population ones. Free + 1 bil gil transfer cap.. plus, that makes it a lot easier to get a house. I used the free transfer to go EU>NA after the expansion, and had around 25 mil gil pre-transfer.. it was a pain to transfer it (bought a bunch of items on the MB, then took 2-3 months selling them on the new server).
