IKEA Homebush (Sydney) Pragel 126cm laminate bencthop in black mineral finish for only $20 (was $55). This is a discontinued size but the colour is still in the current range in other longer sizes. This is a very solid 38mm thick laminate benchtop made in Germany, with postform edge on one side. It's perfect for use as a desk (just add some legs) or in a workshop/garage. It's located in the AS IS Section (near exit/checkouts). Last night I saw there were about 20 left in the pile. Not sure if other IKEA stores have them as the same price, but all the IKEA laminate benchtops in 126cm (except the basic range FYNDIG) are discontinued so they should all be reduced to clear.
