thanks for the responses. I'm based in Oxford so unfortunately no opportunity to come to try your lens but I did get a play on one (mounted to a cannon body) in Dubai airport and was very impressed.
105-300 is exactly what I'm looking for, and frankly wont always be enough either hence the 1.4x teleconverter as well (which should bump me up to just over 400mm). Unfortunately I'm not expecting to get close to many of my subjects (hopefully muller's & albibarbis gibbons, red (and HUGELY UNLIKELY) white fronted langur, Orang-utans and anything else I can find) so the more length and the more light the better. The OS is therefore one of the main benefits of buying a new sigma over the old Nikon I could borrow as although I don't believe the claimed 4 stops, every little helps. ANyway, I'm glad you are happy with the overall lens quality as I'm 99% sure I'm going to get my local camera store to order one in tomorrow.
I think the main danger with the lens is going to be the constant humidity since I'm unlikely to see anything, let alone photograph it when the rain gets going properly, but I already store everything alongside a ton of silica so hopefully everything will stay dry!
