Same here. I was able to score a turkey fryer kit on Amazon for $28 shipped (includes 7.5 gallon pot) and once I had that, I decided to keep going. All I needed was an MLT and an immersion chiller. A little over $200 for the wort chiller, MLT, and turkey fryer kit, and I had everything I needed.
I figured that I would eventually save money in the long run. It's quite a bit cheaper to brew with grain instead of extract. My last brew cost me $20, including the grain, hops, and yeast. It would have been almost double this for an extract version.
