6/8 input audio interface advice

Hi guys. Just wondered if anyone had any recommendations for a usb interface with either 6 or 8 channels? This is to record a small drum kit in a home studio. I currently have the Roland Quad Capture which works brilliantly for me on Cubase Artist 6.5 but obviously only has the 2 inputs. Any ideas would be appreciated. Obviously this may be a dumb statement but I need to record several inputs simultaneously! Thanks!
