Absolutely guys, the mid grade tools are plenty good enough for most anyone. Gear wrenches for example, they work about 90% of the time for me and the SnapOns stay there for when I really need to muscle it on a suspension component or something.
I do have to say that a good tool in your hand makes the work much easier though. It' like the first time I held an American Made vintage Fender Stratocaster, holy crap what a difference from the guitars I had played before. It made playing WAY easier.
My Martin Hammers are so much better than the cheapo's I have it isn't funny.
