I'm a cheap SOB too. But instead of sugar and nutrient, I just batch sparge a pound of malt in a 1 gallon drink cooler and do a 30 minute boil on the stove. I figure if I have enough grain to brew, I have enough grain to make starter wort. I am doing this a couple days ahead of time so it doesn't add time to the brew day. Heck, it doesn't really even cut into my beer drinking time. I can still drink beer, watch tv, post to this forum and make starter all at the same time. Doesn't take paying as much attention as when you actually brew.

Thanks for posting this bug, this was actually my other option aside from using high dollar DME. I suppose making a 5 gallon mash for starters every so often will be in my schedule from now on. I will put them in gallon jars and pressure cook them instead of boiling them and saving though.
