So I'm a couple of months into the whole DE shaving journey. When I started I purchased an inexpensive Shaveway badger brush. To be honest it's done a decent job, but I don't feel that it will hold up for the long term. I'm not in a position financially to really start "collecting", so I'm looking for something solid and functional that will last me for the long haul, and I really don't want to spend more than $25 or so. Function trumps looks, but looks don't hurt either. Badger? Boar? Synthetic? I know it is largely preference, but I lean on your wisdom and experience. For reference, I have soap, croap and sticks and I have a 1963 Gillette Slim and a Merkur 34c if any of that matters.
