I'm getting ready to brew my first batch of homebrew and from what I'm reading here a lot of you seem really down on using kits. because of my work/family schedule it's kind of hard to get to my LHBS, so I was planning on buying a kit online from either Northern Brewer, Midwest Supplies or Austin Homebrew Supply. All of these shops offer various yeast options for their kits and most of their reviews seem pretty positive.
Is it safe to use one of these online stores for kits? Does anyone have experience with these stores?
