Nice. My very first brew was the Liberty Cream Ale as well. It turned out pretty good for the first beer ever!
Like you, I also jumped in head first with making a chiller, but for those worrying about trying it, don't worry. It's really easy! As long as you have something round to wrap the copper tubing around it's pretty hard to mess up. Then all you need are some hose fittings and maybe sweat a few elbows on and it's golden.
Here's mine. Notice the odd tapered shape... it's because the only thing I had was the base of a bird bath to coil the tubing around. It doesn't matter and it works great. I can still get 5 gallons down to 65 in just about 10 minutes
