Are they really worth it? Are their benefits purely for visual observing, or do they provide any benefit for astrophotography?

Matt from T&A has them on sale (1000 oaks brand) for AU$140 and i'm planning my next purchase because i'm getting some cash from some relatives for xmas, plus my birthday is only a month and a bit after..

When the clouds eventually clear in 2007 i'd like to think that i'd enjoy using one to enhance the contrast of the nebula..

A few guys (Dave47Tuc, others?) own both the OIII and UHC.. what's the best one, which one do you use the most? I've read many times that ideally you want both because some objects are better with one filter and some objects are better with the other.. but i'm not going to get both right now, so if you could choose only one, which one would it be?
