The Iwata brand is the way to go but for your budget try mugendo budogu carries a tetron hakama.
Good prices. Maybe I'll check them out the next time I need to order one. The only thing that worries me however is that the only size measurement is the length. I believe the really important measurement for pleated garments is the widdest point of your hips. As far as I could tell they don't offer different girth sizes.
