have you looked on the barter board I've had a request on how much something costs since last night and no answers and half the other pc on the board haven't been answered either and some have been on for days
I can't say for sure how much it's worth, but I can say that, for scythe, 20% enchanting is probably worth more. Fortitude is great for most other weapons, and it's still good on scythe, but since Dervishes have the inherent +25 health and use so many enchantments, enchanting will probably be a bit more.
Of course, that really doesn't help you much. You'd really be better off going to the Guild Wars Guru trade forums. Just google Guild Wars Guru and you should be able to find it. It's a pretty useful resource for any trade related queries you may have. You can also use the auction area on Guru as a tentative pricing guide for a lot of different items. --- La fille danse quand elle joue avec moi, et je pense que je l'aime des fois.
