I'm making a Star Wars forum.

[SaturnVengeance]

I would like to create a Star Wars message board, but I'm not sure what forum software I should use. I like vBulletin, but I don't like the idea of having to pay $285 for vBulletin premium (or even $175 for vBulletin standard). I like InvisionFree and ZetaBoards, but ZetaBoards doesn't look very professional, and InvisionFree doesn't have a couple of the features I like. I also like MyBB, but but the only free hosting company I like (x10hosting) has a lot of downtime and is really a hassle when setting up a domain (which I still haven't figured out how to do with x10hosting). I plan on this Star Wars forum being really popular and look very nice and professional. Is it really worth spending a lot of money getting really good forum software, a good hosting company, and a domain? Me and one of my friends made our own forum once, and it's a nice little friendly active community, but it's run on ZetaBoards, whereas I want this Star Wars forum to be huge with thousands of active members. What do you recommend? Thanks in advance.
