Buy carefully. Get the very best you can afford even if it means that you have to wait a year. You now have one that you can make do with and wear without concern of getting it dirty or burn spots at the odd campfire. Get something from a person you feel comfortable with; preferably someone who you can go to who will measure you. Look at fabric samples. Try out some different weights.
Getting great quality for a bit of cash is better than getting several cheaper that you regret and is cheaper in the long run. You will have a good kilt for the rest of your life.
