Interesting thread to read.
I don't believe I can add much but only reinforce what has been stated about using what works for you. Some people will see value in a $70 soap or $300 brush while someone else will relate that to overpriced snobbery. It's in the attitude as to how people relay their opinions.
I myself enjoy the hype sometimes and relish in trying new products, they are definitely not necessities I know. I too have a couple of old $30 straights that I get great shaves out of. I haven't managed to succeed with the gold dollar yet but will get there. I also like the feeling I get when I have used something much more expensive. No science to it, I just see it all as my stuff and months later, whatever I paid is irrelevant. I just enjoy using it all.
With no ultra high end gear, maybe just some good soaps, I have no reason to show off.
Sharing in any threads about Sotd, acquisitions, what did you use today is only a factor of my satisfaction and allegiance to these threads, brands and the hobby it has become.
My family will not understand it if I tell them what I used today but the forum gets it.
