Joel, we all know there are anomalies. For example as far as I can tell this one http://badgerandblade.com/vb/showthread.php?t=81810With that said - thus far using historical data - Livi's are the worst investment of any production razor. I don't buy the whole "smaller market of buyers." Put up a TI, Dovo, Tim Z, Ellis, etc etc with a reasonable price and it's gone in not time flat. Do that with a Livi... and you're in for a long sale.
is still not sold 7 months later, despite multiple attempts. And I've seen mid-range TIs have to go down to 50% off within few weeks before they can sell.
I'm sure that given the price increases of current production razors in the last two years you can sell a lot of your TI razors, for at least double what classicshaving used to sell them in the old days, not just the tiptles.
Should we mention the filarmonica brand - that's gotta be one of the most profitable 'razor investments'.
At the end of the day though, most of us buy razors to keep them, not to resell them, but I can see how to many it is important to hedge their bets that a razor will be a keeper, so your point certainly has merit.
I don't have the experience with as many high end razors as you do, but so far it seems that most of my impressions are consistent with other people's who have more experience than me, like thebigspendur, mparker, and lynn to name a few, in many cases with yours too.
