My perfect cutter is not so perfect anymore (is biting the tip instead of cutting it), will send it to make the lifetime warranty effective but...that made me start looking for a new one. After looking around these four stand out:
If you are looking at spending that much I would suggest a Xicar XO cutter. Mine is as sharp as the day I got it over two years ago. Cuts up to 64 ring gauge and can fit in my pocket without having to worry about it opening up as I travel. Mine ran around 90ish at a local shop.
