I know the topic has been beaten to death over and over and over, but I'm not sure that horse is dead yet!
If I live to be 1,000 I'll never understand someone asking where to get the cheapest ___? The tools you select should not be about the price... If you are making your buying decisions concerned about the price, you are off in the wrong direction.
Tools are something you're going to have the rest of your life; buy once, buy top quality and buy a name brand that you're going to be able to get parts for in 20-years should you need them.
And if you didn't know the tools that you get from the home centers and discounters are not the same quality-wise as the ones that you get from a professional trade supplier.
I've said this before, and probably sound like a broken record by now, but it bears reparing here... the best advice I can impart on you is to keep this in mind... I have never once said to myself; "Damn, I wish I would have bought the cheaper one." But, I have said; "Damn, I have wasted money buying that cheap POS".
