Carbide Burr bits good source?

3 for $60 for good carbides is cheap.
really? Don't seem like it. though I have had some crappy ones before, too long ago to remember what brand they were or how much Id paid... the cutting "tits" broke off, and the bit "burnt up" ,much like drill bits do, threw those away too long ago to remember. I don't need/buy these everyday and IDK who is "good" or not, or really what life expectancy I should be anticipating from them but that Snap on is definitely overpriced due to their "ego"
IDK what to reasonably expect to pay for "good" ones I want best bang for buck.
The 6" ones I got from Benchmark are... SH-2L paid $10.99 SF-3L paid 11.19 SB-3L $12,49 and SD-1L for $8.79. plus a few packs of air saw blades (which were on sale) to boot.... we'll see how good they wind up being.
Ill have to go out to my truck and get the receipt to tell which ones I got from Fastenal, though those are std length.
IO did get 4 from them but they gave me 1 free because "it didn't come up on their system" so that diluted the $60 down to a better price, still seemed high to me at an avg of $15/ea among the 4. but the 3 I paid for avg out to $20/ea. I don't like to pay big money just so I can brag about having bought "X-brand" anything. but I like what I DO buy to work for me as expected. I have an HF store by me that I browse 3-4 times a year but usually walk out of empty handed. What I have gotten there has not done as expected and ends up in the trash in short order around here. I don't like throwing money away, and buying "cheap tools" for the sake of being cheap is the best way to do so. But I don't like paying Snapon prices either. I just bought a set of Phillips screwdrivers for home off the S/) truck a few weeks ago because I suddenly find myself with no Phillips at home and what I do have just slips/cams out under the least of pressure....what I had here, is/was a hodge podge of brands I didn't like paying $100 for that set of ~6 or 7 screwdrivers either. but they grab and they work.
