Digital Camera Debacle

So, now that I'm going to Sydney, I want to preserve some of my memory's of the place by capturing them on a camera, which by now you have probably guessed, that I don't have one :P

I was looking to purchase a Pentax Optio A30 (the "A" series is the most advanced of Pentax's Optio range), but since it's near impossible to get one due to the announcement of it's successor (A40) which is due out some time in February, I am stuck with a very difficult buying decision...

Do I buy the older A30 or do I risk it with the newer A40 model, which could be potentially unavailable (I need this by 6/02/2008)?

My friend has already bought his (not so practical, but awesome) camera, and he is trying to convince me to buy the A30.

Because of this, I feel a bit boned...

I have decided to buy a JVC GZ-HD3 video camera instead :)
I just hope it arrives in time for me to configure it (play around with it) before Sydney...
