Haven't been on the site for awhile but with the new season coming I've been doing some lurking and this caught my eye.
I got that exact kit for my birthday last fall and have put out 6-7 batches of 2 cases each, mostly Brewer's Best kits. I highly recommend it, to me it's been a fun hobby especially in the winter, and I like the taste of the beer if you follow the directions to the letter. I've even started creating my own recipes. It definitely has a unique taste - more hoppy and bitter than your typical commercial ale. But by now I'm to the point that I would drink mine over most commercial beers.
The time commitment isn't too bad either - count on a 3 hour slot with lots of waiting in between to boil and bucket the wort, then a week or 2 later maybe 2 hours to do the bottling. Set the oven timer for the first part and it's perfect to do with the game on. One of the worst "chores" would probably be all the sanitizing, but as mentioned, it is critical to keep bacteria out of it.
Also about reusing the bottles - it's not about the cost, as they are only 10 cents a piece. Really I think it's just a culture thing and a way to avoid the chore of peeling labels off reused commercial bottles. Trust me, they are far cleaner than the glasses you pull out of your cupboard.
And finally one of the funnest parts is giving it to people as unique inexpensive gifts or just for your buddies to try. I have several "miller lite-only" buddies who consider it a treat when I bring a 6-pack with me for a poker game.
