It has been 15 years since I have done any significant brewing, but you should be able to get large blue cast enamel pots at any 'farm and fleet' type store for a whole lot less than $85. These are large enough to cover 2 burners on your stove, so there is no need to break the wort into more than 1 pot. Google farm and fleet and you will find Blain's in Illinois, and Mills near Milwaukee and some others. Give them a call.
I loved brewing, but it is a long process and takes quite a few trys to get right. Your biggest problem will be keeping everything properly clean. My best suggestion is to buy high quality liquid yeast and give it a big head start. You cannot put in too much good quality yeast.
