I'll most likely go for the p150, I've been checking around the digicam forums and site's and noticed that there's a new one coming from Sony (p200) in February if I'm correct, so as soon as that comes out the p150 price should normally drop drastically! So I'm rather certain I'll go for it.
Do you think a 256mb memorystick will do? Also I'm really have no idea about stuff like this - so could you tell me approximately how many photo's you can take with such memorystick? You think I should go for the 256 or 512?
Will also check those Canon models out.
Thank you for all the effort that you've put in the reply, really appreciated!
