I have a english iso taper 68x107 bb.

On somewhat of a budget and lazy to buy tools that i didnt want to replace my bb and so i am just buying a crankset.

Im down to two choices from CL.

used miche primato for 75$, no pics, have to see it to determine condition
new vuelta pista for 40$ plus he will deliver

Im leaning towards the miche, but is the 35$ more worthwhile? Anyone have experience with both of these cranks?
