heres a link for the 120cm wide one only £29.99 now. 180x120x45 shelving
sure i paid £35 on ebay for one of these. had 2x 40cm deep 90cm wide for around £20 each and one with these dimensions for £35odd.. seems expensive at £61 edit.. just checked it was 120cm wide 180h and 45cm deep for £31.95 new.
These are good, we've got a ton (figuratively speaking, although maybe literally too...) of cable reels sitting on some, shelves are thin crappy mdf but well supported by the metal edges and cross members can't see them ever sagging.
