need a simple question

im doing this for a friend.

He want to distribute internet across a building at 14 locations at fixed bandwidth between 64K-512K. But the investment is tight since its all coming out of personal pocket.. and there is no real beed of flashy vlan features. So what are the simplest, cheapest and reliable switches there which can control bandwidth on port basis.

I did my search on google and came up with tons of product…but since i havent used them.. i cant trust manufacturer claims.. therefore i am doomed to rely on experience of TR members.
