Morning Shedman,
It depends what you want really, I've just been through this, and ended up opting for one on e-bay, buy it now. There's a lot of companies who sell through e-bay as a way to reach a bigger catchment. So there are brand new as well as pre used..... It might even be worth checking something like freecycle or pre loved, if you don't mind a pre used one.. quite often people will be giving them away if you go and collect.
I found it easier to compare like for like on e-bay and then I double checked by googling just to make sure. It was delivered to my doorstep in perfect condition within 3 days!
If you want advice on what to go for this is the right place! The lovely people on here are a wealth of information
Good Luck
