I don't know if your server is expensive or not, but you can get goblin gliders for 10g. In my server it was more than 10g so this was useful to me. If you go to the center of dalaran with the portals to karazhan etc. There is a goblin beside the dalaran crater that has goblin gliders for sale and she will sell them to you for 10g. These gliders are pretty awesome if you use them in conjunction with a few toys.
