All joking aside Chris, that is a fairly decent bit of kit for £1100. It would be hard to find something with similar performance for £1500 tbh. Even the 'Qute, which is a top notch bit of kit, is £900ish in Mark 2 form.
I smell a rat with that add. The going rate seems to be £1800-£2000. Still, with cash on collection or PayPal protection it is worth a go for £1100. You can always bang it out for no loss if you don’t like it
