Well i had been considering making a wow profession kit and after seeing the guide on the front of tuj i decided to pull the trigger. It took my about 2hrs to put it all together. I was able to get all the materials off of the ah with the exception of stranglekelp (pita to farm). I had to pick up two recipes from vendors and put it all together.
My total cost not including vendor recipes or stranglekelp was 2264. I was able to sell within about 3 hrs for 11k and i had people asking me for other kits too, mainly lw.
IF you have the time i think there's some serious gold here.
