A quality guitar for 80 quid? You're gonna struggle there, man - unless it's second hand.
In my experience, though, you don't want to buy a second hand guitar online.
There are some good cheapish
Epiphone acoustics for musicians just starting out, and
Yamaha makes some good starter packs.
My advice would be, if you haven't heard of the brand, don't buy it. Of course there is always exceptions, but it always helps if you're buying from a well-known trusted guitar maker.
Otherwise, like ClockworkMonkey said, go out and get yourself a nice acoustic from a local guitar maker or music shop.
