Alright tech-savvy (and other) DiSers, I need some advice and guidance.

I need a dictaphone. By Monday. Preferably one that records in a format I can import onto my computer and listen to in media player or something like that.

Any recommendations of brands?
Which high street shops which are likely to sell good ones? Obviously I've left it a little late to be comfortable relying on Internet/mail order, but I didn't realise I'd need it this soon.

Help pls? :)
