Im new here, but wanted to add my 2 cents.
Ive been a shade tree mechanic since I was a kid fixing whatever using my fathers older raised panel craftsman tools. I am also a professional mechanic who has worked in shops as well and now I do mobile roadside work for an AAA contractor (went back to college to get a degree part time) where we mostly just drive around selling batteries off the trucks.
The tool trucks are great if you have no credit and cant afford to shell out the money all at once for tools. You cant do the job with little to no tools-just doesnt work. In every single shop but one (and I know the owner and all the workers personally) most guys wont let you near there tools without putting a deposit down or swear you will return it (and if you dont OMG! RUN!). So yea the truck makes sense. However a 200 dollar craftsmen set could do most of the job with some other items thrown in from sears.
I used to own a vast collection of snap on, matco, mac, and so forth. Over time I realized the tools werent always better and the tool truck guys could be HORRIBLE (skipping you, taking forever to get a tool or warranty it, flat out refusing warranty, etc). I had quite a few bad dealings and now very rarely do I buy tool truck stuff. On a related note in the 60's my grandfather who was a machinist/fabricator ran into the same issue-tool truck guy was such a jerk he sold all SO and went to CMan.
Anyways I had to sell alot of my tools off as well due to a few financial problems and was left with barely a basic set. This time around I checked online and found stanley/husky stuff was good enough for awhile. Low and behold I have been using the same box of tools for my AAA job now going on 8 years. Same tools, all stanley/husky from about 8 years ago. Only thing I have ever broke was the ratchets b/c I use them alot and honestly since they are so low cost Ill admit I used them as a hammer alot for certain things. I just buy a new one (although they changed the design and I dont like them now) for about 10 bucks or I called stanley or went to home depot. Every tool in my AAA box is a non tool truck brand. Pretty much never had an issue and I use and abused it all. Interestingly enough I thought maybe CMan raised panels would be a step up. The tooth count I learned is less and they dont mind dirt/grime as much. I broke a 3/8 and 1/4 ratchet so many times and swapped so many times i threw in the towel on them. I think after 4 3/8 and 6 1/4 drives (and the last few I demanded come brand new out of the case at sears not rebuilt) ****.
Now these days I have a large collection again, almost all of it purchased at home depot and husky/stanley branded. Amazingly its all held up great and I have had no issues. Still got some very nice SO, Mac, Matco and SK stuff tho. But my point is the tool trucks-yea they sell alot of good stuff-but better deals can be had on plenty of good stuff. Back in the day this wasnt possible, it was either sears, SK or buy tool truck. Now with the internet and pretty decent tools being sold in most stores the average person and the pro is mostly happy. Tool trucks still useful for specialty stuff tho. Example: 10 years ago I bought one of the first snap on cordless impact guns. I LOVE THAT THING! 2 years ago I finally got the new one, and its way better. Are there better things out there-sure by now almost every big box store has these guns and in some cases they aint to shabby. But that impact gun has changed probably over 5000 tires, been used to work on my own stuff, work on stuff in shops, brought to pick and pull yards to yank stuff off, used to drive big bolts into home construction projects-you name it. Well worth the 800 bucks (I got the kit w/light 12v charge and 120v charger and 4 batts) I paid. Finally the ni-cad batts are starting to fail but it is pretty old.
Anyways thats my story.
