Home Gym? (Upper Body Building Exercises)

Me nor my parents know what to get me for Christmas. I thought a Home Gym would be OTT until I realised they are not that dear!

The thing is in college:
We're always doing strength in the gym and I'm kinda shy on the weights and don't feel confident enough to lift to my potential. I was thinking if I was to buy one myself it would benefit me. It's convenient to me whenever as it's easy access and I dont have to travel (well i'll be travelling up the stairs).

But my Mum said she'd consider buying me one for around £200. I've found one but she believes it's too big - I believe i can make room for it. here it is: http://www.argos.co.uk/static/Produc...uctInformation

Could anyone find me reasonable machines for the price range??
