£120, pictures was crap wasn't expecting it to be that good when i got
Got an everlast one in the sale at Argos for a decent price which must be quite solid as it holds me depending on what you want theyve got some on there now starting at £50 with weights (although no much) included
tried these http://www.gumtree.com/ i would contact a small local metal work company theres not much to a flat-incline bench and theres will be industrial strengh, most home gym brands dont last long IMO
Aye gumtree is the best place for this. Might even get someone giving it away, and you can always haggle with someone face to face and they're likely to knock a bit off.
