I was planning on getting a Joby GorillaPod, but according to some users here they are a bit rubbish? I am thinking about the GorillaPod SLR, as it will be small enough to fit in my bag, and it does have favourable reviews from other websites.
Thanks for that, to summarize: Long exposure, high ISO (1200+?), lowest F possible. I'm going to go out and do some decent night photography practise when I acquire a tripod/tripod like thing.
