I paid $1200 for mine and it was originally $1700. the only alteration I will need is some padding (gotta fake the boobs), so it shouldn't be more than $100. I had promised myself that I wouldn't spend over a $1000 but I tried all the David's bridal ones and a few other less expensive brands and I just didn't fall in love. My bridal consultant brought in my dress to show me the color on the sash and I had to try it on!
Don't worry about the "knowing it's the one". I thought something was wrong with me too because I sat with my MOH and mom for a good 40 minutes going between two dresses. My dress didn't make me burst into tears or scream or anything like that so i doubted it for a bit. But I went back to try it on again with all my BMs and I just loved it!! I didn't want to take it off!
Oh and the back of the dress is extremely important!! That is what everyone is staring at the whole time...you at the alter, you walking away, your first dance, etc. Its one of the reasons I love my dress so much
Here it is to prove it...the back is more ornate than the front:
