Belly Support

Hey ladies, can anyone recommend a good belly support band or belt? I'm 26 weeks and measuring a few weeks ahead in the belly, but I'm a fairly small person 4'11" add that in with having a needy 10 month old that constantly wants to be held and walked around and living on the third floor of a stairs only apartment complex and some days my back is just KILLING me! Don't want to spend a lot of money on products that won't work so help would be appreciated if you've tried some already :)
