Welcome to B&B! My suggestion, have a pre-determined quantity...number of razors, and dollars you want to spend, otherwise you will want all of the vintage razors.
Lol, welcome to the rabbit hole! If you don't watch you will have a dozen of your favorite razors and thousands of blade you will never use!
To say nothing of brushes and soap....
I now have three FatBoys, two Aristocrats, five Slims, five Superspeeds of various ages, and 2600 razor blades, and average 70 shaves on a blade. Plus an unknown number of Old Types and Techs, I've lost count.
