Activity table - worth buying?

My DS2 is 7 months. He is extremely active, crawling well and just beginning to cruise using the furniture. I'm finding it hard to keep him entertained. None of the baby toys we had for DD seem to interest him for long at all. I've been looking at activity tables. He loves noisy things and pulling himself up so thought it might be good and although they're not expensive, I don't want to buy another plastic thing to clutter up my living room if he'll only play with it for 5 mins. Anyone got one? How long did your LO use it for? Worth getting or a waste of space? Thanks!
