buy belkin , they r of better quality, as ur budget is 1k buy powered usb hub u will get an power adapter with the usb hub, u can get 'belkin 4port powered usb hub' frm infibeam.com , sedna makes usb 3.0 hub but price is more than 1k
of course u should get usb hub with power adapter, if u connect mouse or keyboard or bluetooh dongle the is no need for the power adapter but if u connect usb modem or external hdd or external optical drive u will obviously need the power adapter, coz single usb from desktop or laptop simply can't provide so much power
