Build it. Not sure where you get a kit from in london though. I did build one about 15 years ago. The kit had a concave mirror, the eyepiece and the prism thing and the bits to connect to the tube. I used a cardboard tube from an old fabric roll. Was cheap and effective. You should easy be able to get a kit that allows you to see Saturn, Jupiter and it's moons ect.
I never bothered with maps and stuff. Just pointed at interesting points in the sky.
