I admire your enthusiasm. You will find that there is a lot of crossover with regards to the process of fermentation, sanitization, racking, care, etc. I would suggest that you pick one to try out, and go simple to start as it pertains to equipment. I had a lot of ideas when I started, but ended up going with the 60 buck kit, and I am glad that I did, as I now can just buy those pieces that I want bases off of my experience, limited as it might be. My best friend does wine, and he is the one that pushed me over the edge to start brewing. Since I am a beer guy and not a wine guy, I went with beer. We still get to talk a lot and share experiences. One way or the other, the experience that you get with one will help you with the other.
slainte!
