Cheap w/poor quality? or Spend slightly over budget with couture quality?

So, my first question to all my clients is always, "What is your budget for your wedding dress?" It seems that everyone, including myself, is always looking for a great deal!~ And who can blame them?  I'm always trying to look for a bargain!~ But the truth of the matter is, making a custom designed wedding dress that is catered to your taste level and fitted and re-fitted to fit your body mold, it can get pricey.  But the difference b/t store bought and custom made is quite significant. Store bought is generic, and can fit but not perfectly, therefore having to pay extra (at some places) to have it taken in.  Where as custom made, all the fittings, your choice of fabrication, little details only you can decide on are all included.  So my question i guess is, as a bride, what would you rather have?  Would you be willing to pay slightly over budget to get that wedding dress of your dreams?
