I have a fat boy and a slim, and the slim is hard to beat. It would definitely be my “stranded on a desert island” razor.

These prices in this condition are pretty high compared to ebay. I'd make sure to haggle on this. That fatboy for $55 is insane. $35 for the red tip is right at market, offer $30 unless you have a few that you are picking up. What's the price on the slim? I'd offer 100 for the fatboy, slim, and red tip, and ask to have them throw in either the gold fat handle tech or the super speed flare tip next to it. If they were polished and adjusted these prices might be more in line. I have a huge collection of these vintage Gillettes and buy quite a few in found condition from various local and online sources.

I know what you mean. Some people are definitely on the make. I’ve seen listings for razors I’ve bought asking for 3x what I paid for mine. I’ve seen the most inflated so far today, though I suspect there have been even more outrageous examples. Try a Slim for the equivalent of $551 not including postage. It’s just a regular 1963 I4 Slim. I paid the equivalent of $40 for mine 14 months ago in similar condition and that included postage!
