Go for it! I have the same one and I love it. It makes water changes so much easier to do, I can't imagine having to haul buckets for my 56 gallon tank. I made do with a siphon and buckets until I got that tank, and it's one of the best purchases I've made as far as fish stuff goes. Just be careful with the valves you turn to change from siphon to fill up, I've heard a few reports of them breaking. Also, you will probably need to buy an adapter for your sink faucet, but those are just a couple bucks at any hardware store. Just bring the part that screws onto your sink and the aerator for your sink faucet and the people at the hardware store will be able to find the right one for you.
