Coopers Lager (not really a lager as has been mentioned) was was my 'gateway' homebrew. Even though I am all grain now, I have likely not made my last coopers. As people have mentioned, use dme instead of sugar for the fermentables (sugar for priming is groovy in my books). If at all possible, try to keep temps in the mid to low sixties. My first ever coopers kit (where i used sugar and had temps hitting high 80's) tasted very cidery. In fact if I hadn't told you it was beer, you would swear that it was apple cider and didn't have a single drop of beer in it.
I still drank it, I mean what the heck, I've never been known to turn up my nose at a beer or a cider for that matter.
Like all hobbies, your second attempt will be better than your first, don't get discouraged if your first batch doesnt turn out exactly like you expect. Of course I might be biased as I would rather drink a botched coopers kit than a lucky or a carling anyday, although the occasional lakeport is one of my guilty pleasures.
