I actually ended up with a mix of 205/103 at a ratio of about 60/40. .5 ounce of 205 at $29 from Amazon and .5 of 103 from Zoro at $19. Five bucks for a glass 2 oz jar and you end up with a lifetime supply for $55.
Considering the amount of switch lubing I do, it is pretty much a no-brainer for me. If you are only doing one or two boards, then I definitely see the appeal of getting the smaller amount and being done with it, but bulk made more sense to me personally.
