4 years or so now. Started in college in summer '08 and brewed through fall '10-spring '11 when I brewed a few dumpers since I was more focused on school. Sold a bunch of gear (had about 20 kegs, should have kept them) to fund a final summer of freedom before my senior year of college and that was that. Put my time and (soooooooo much) money into a project car when I finished my undergrad. Worked full time and did my masters in 2 years.
Now I'm getting back into it- kept 6 kegs, a few carboys, kegerator, 2 co2 tanks,a bunch of taps and odds and ends, but my burner/kettle/mash run are all gone.
Its kind of nice as it affords me the ability to essentially retool my brewing entire setup without being "out" extra money of old gear sitting around. I'm going to be doing 2.5 gallon batches, fermenting in my kegerator in cornies with a homemade brewPi temperature controller. Will be doing closed vessel racking/carbing and bottling with a bottle gun. I know bottling will suck but this will give me a lot more control over my fermentation control and ability to make different beers and store them without having to clear taps out for new beers.
