Sparky, the problem with buying cheap V bits, is that the point of the V bit is not really a true "point" and your cuttings will not turn out correctly. I use the CMT Lazer V Bits and have been very happy with them. I usually wait until they go on sale
Search amazon for: cmt bit V 1/4
They are a "little"costly, but in the end, they last and you'll be very happy with the quality.
A note on what is best as far as what angle, depends on the application you're doing. What software are you using?
