tbh, i wouldnt go near that stuff
http://www.fitness-superstore.co.uk...grip_olympic_weight_set_7ft_bar_/12593_p.html
that is the bare minimum i can suggest tbh, it will hold its value and will last forever unlike "vinyl" which could only last you a short while.
you will also need matting another £60-100 easy
then a decent bench another £150-200 easy
join a gym, stop looking for a cheap option, cheap options are cheap for a reason.
ebay and 2nd hand from gumtree is worth a shout for olympic gear, but seriously a home gym will only be as good as how much money you throw at it.
