I buy Snap-On tools (the best money can buy) and they are pricey. However I get the service I need. If you buy from Randy not only do you get the quality expected but the service to go with it. Can you call Tower and ask a question and expect a response you can depend on? You can with Randy!
I am considered a good builder (expert) However even experts consult with other experts.
Thats why they make books! I hope you get the drift...
