@NJM48... Argos... good times - had a fistful of Argos vouchers that got me 1/3 of the way there
I was using OfferOfTheDay.co.uk to monitor the price. I think John Lewis went down in response to Argos, but then JL quickly went out of stock. Then Argos were very close to out of stock too - I found one of about 3 that were available in the entire Midlands. Tesco's have run out. OOTD only have Asda left (that's Walmart, Colonial Cousins) at £359.
The 720 looks like it's going to come in at near twice what I've just paid. Basically that is for 5.1 sound (that I don't think can possibly work that well on a built in mic), and the Wifi thing, which is a nice party piece, but really how much will you use it?
I'm well chuffed with what I've got. I'm looking hard for the right case to keep it in - I want a close fit, I don't want to keep accessories in with it as I have a bigger camera bag for that, and I don't want it rattling around either. I went into Currys today to try the Lowepro that you have, I kind of liked it, but the opening looked a bit tight for me to be squeezing my £300 camcorder past more than once or twice. Currys also had the Lowepro Apex 100 which was a good fit in two dimensions and had a separator, I'd have bought it if it weren't £29.99 - my credit card has had enough for now
Also @NJM48 your John Lewis £299 buys you an extra year's warranty, that is worth £20 of anyone's money so I wouldn't worry about not having had the best deal, I think you have.
