I just purchased two pieces 460mm x 625mm 5mm thick and polished edges for $50 for a tv cabinet that I have just converted just need working thermostats now (thats another story). I didn't shop around , I just used G.James Glass because I have used them before and they gave me really good service. This should give you an idea of price but I think if you shopped around you could possibly get it a bit cheaper but for me I thought it is well worth the money.
