Spin Bike For Sale?

[fanny1]

So I want to try and get my fat Ar*e into a bit better shape and a friend has recommended I get into spinning. So I am looking for spin bikes for sale (preferably second-hand) I wonder if anyone else here is into it and has a bike at their home? I don't know where to even start looking! I'm a bit lost!!
A quick google search has bought me this *link... can anyone help out??? Thank you x
