I've had a very lucky morning - a tax rebate and a pay rise, so I'm looking to replace my ageing sofa. I'm after a decent corner sofa with a budget of £700 or so - is that ambitious or perfectly doable? I've had a look at the Argos Go Create ones, and they seem alright. However, I'm no sofa expert - it's my first place - and I'm sure there's a bunch of you who know way better than I do with this sort of thing. I'd appreciate the input
