Found a good Canadian deal (C$500/US$410) and bought one.
After buying the sigma 100-300 last month, my 2 kids (6 & 9yrs) want to come along every time I go to the park for birding. Problem is, each one is arguing who can use my old but trusted P&S (Canon A610). Stress level has gone up every time I hear them in the background reminding each other "it's my turn", or how many shots, minutes, etc, the other one has left. The only solution (best) I can think of is buying a small camera but instead of another P&S, got a KM and let my 9yr old daughter use it. She's only 9 but a big girl (5ft) and the KM fits nicely in her hands. Now I have a small camera for travel as well. I don't care about the review, bought one and very happy with it.
Here's the first few shots I took with the sigma 100-300mm.

Lastly, we're all happy shooting together.
Thank you very much for looking.
All the best.
