I'm a very patient collector and have a small collection (under 10) razors. My favorite's are the Filarmonica #12 double temple and my Erik Anton Berg with custom scales. I also really like my Theirs Issard I'm very fond of as well.

I have been looking for the following and will continue the search because after all that's part of the fun!
Wade & Butcher 6/9 or 7/8
Filarmonica #13
Dubl Duck
Joseph Rodgers & Sons sheffield

Hopefully I'll stumble upon some of these but I'm not willing to pay the inflated eBay prices or take the risk of buying a crappy razor from there.

How do you guys manage your collections?

BTW I don't collect for $$$ I just like shaving with cool razors!
