I can honestly say I've never thrown any kit brew away and they've all been drinkable. I used to think there wasn't much difference between a cheap kit and an expensive kit, I just added a more flavoured sugar like a muscovado or soft sugar to modify them a bit.
Having had a wherry bought for me for chrimbo though, I can see where the extra expense gets justified. Even though I think the Wherry isn't the best kit for me it has produced an excellent quality brew and I've had worse from the supermarket. There's just more to it than in some of the cheaper kits, and if your going to buy extras to bulk up the flavour in a cheap kit why not just buy a better kit in the first place

. I'm going over to the dark side though and looking to brew big batches so whilst kits aren't completely ruled out, at £20 or so for the better ones I think AG is the way forward, for me at least.
Out of all the kit brews I've done though, My favourite has to be the Coopers Wheat Beer, Can't say any more than it must just suit my taste buds.
