Buy the Joby brand original at Cathay. SLR ZOOM is about 80++ . I bought it. Do note that SLR ZOOM does not come with the movable joint unlike the SLR version, thus its very hard to angle it without a ball head. My ball head is too heavy and bulky to use effectively with the gorilla pod, so thinking of getting a small cheapo ballhead for it.
To be honest, the best horilla pod is the small one used for PnS, that one is fantastic and supports well and is super useful. DSLR ones not so, since you can't use a battery grip (raises the CG and increases rotational force, so it falls easier).
The big tentacles don't grip as well as the small PnS ones, since they are harder to manipulate.
