I am just about ready to buy a big, lockable tool chest. After that (very soon) I will be filling up said tool chest with lots of new tools. So, like you, I have been looking around a lot lately for a new starter tool set for the shop (I have had lots of tools over the years, but always bought cheap ones because they kept disappearing out of the shop. Now many of those sets are incomplete, so let's just say I'm basically starting from scratch, and will be looking to buy "good" tools I plan to keep forever, now that I will be able to secure them). So I'm basically in the same position as you. Anyway...
I looked at the Craftsman sets, they seem pretty pricey and have a lot of **** you don't need. Lots of allen keys, bit drivers, and 12 point sockets. When considering $ per piece, really take a hard look at what all those
pieces are, exactly. Nowadays, they seem to get that piece count up by adding in a lot of fluff.
What I have decided I am going to do is buy a bunch of basic tools at Harbor Freight. I might get flamed for this here, but I have been looking at their Pittsburgh hand tools and they look fine to me. A full set of wrenches (metric or SAE) is right now on sale for $9.99. I figure for a couple hundred bucks (maybe less?) I will be able to buy all the basic 1/4, 3/8, 1/2 sockets (deep and shallow), ratchets, extensions, screwdrivers, and wrenches without getting any **** I don't need. I am basically "making my own kit" for the same money, or less, and getting exactly what I want, to start out. Try to do that at Sears, and you will be spending $400+ (maybe more?)!
I am sure I will start out mostly with things that are on sale (a lot of the basic things just happen to be on sale at the moment). Then I can always go back later and pick up other things as I need/want them, or in the case of HF, as they go on sale (watch those flyers!).
The Pittsburgh tools have a lifetime warranty, although I have gotten different answers from 2 different stores I have asked about needing the receipt or not (one said yes, the other no). I will note that the official policy of HF is to require the receipt (I plan on keeping all my new tool receipts safe and sound in one of the drawers in my new toolbox,
just in case 
).
I dunno, I just think Craftsman have gotten too expensive anymore, and they are not much better than what you can get at HF for much, much less money. And the HF stuff has a lifetime warranty anyway, so what's the difference?
Here's another comparison: I bought a full set of deep drive, 3/8" impact sockets a couple years ago at HF for 19.99 (iirc). I don't know what they go for now, but probably not too much more than that. They also came in a nice blow molded case. The same set at Sears is probably $80-90. Now that's just getting ridiculous. And I don't even want to know what Snap On would charge for something like that.
Anyway, not to go off on a rant, I'm just sick of being squeezed all the time by big companies. Thank goodness for HF and competition. Check out their stuff, their hand tools are fine and getting better all the time (the latest HF wrenches are shiny, thin, and long and kind of almost look like Snap On ones, lol). Also their toolboxes are the best bang for your buck right now, by far (I will be getting one of those too!). I would continue to be careful exactly what you buy in there though, there is still plenty of junk (electric tools, etc.).
