It really depends on your skill and level patience if you're strictly a home mechanic. If you don't go much further than regular PM and tune-ups, I would say bypass the max access stuff at Sears. I feel like a regular socket set is more versatile. Years back, all I had at home, in addition to a set of metric and standard wrenches, was a 3/8" set of shallow sockets, and a few deep sockets I knew I needed for certain jobs on my Jeep. As my interest picked up and my skill level advanced, I branched out as necessary. **** on the Haynes manuals all you want (though I don't really hear it too much on GJ), they served me well as an inexperienced weekend mechanic -- reading up on a job before I did it gave me a good idea of what tools would be necessary. Over the years, I've actually needed a pass-through ratchet ONCE at home. I couldn't wait to get mine from work, so I borrowed a friend's.
If, however, you're aiming at a full set and want to save some money, you're making a mistake. Those kits are handy, but they won't do it all. I've got the old Armstrong set, and while I swear by it when it's absolutely necessary, it's just not practical to always use.
PS: redundant? tools? Come on now, this is garage journal.
