I guess a lot of it depends on what you are used to drinking. Before getting into homebrewing I almost exclusively drank Molson Canadian and Labatt's Blue. Specialty or imported beers were reserved as a very rare treat. The domestic Canadian stuff is expensive to begin with ($2 per bottle - we're taxed to death) and the other stuff is rediculous.
I found that with a Cooper's Canadian Blonde beer kit (including the yeast) and a Munton's Beer Kit Enhancer I could produce a beer I enjoyed at least as much as the Molson and Labatt's beer I was used to. I did however ignore the temperature and fermentation time listed in the instructions. I ferment (primary only) for three weeks at 18degreesC and then leave it in the bottle for at least three weeks before cracking the first one.
Opinions are like arseholes: everyone has one (and sometimes they stink
). Here's my opinion. Coopers kits aren't that bad as far as I'm concerned. I've found a couple that I like and I'm currently exploring ways to make better beer using them.
