I too, am a DE user. And like a few others on here, I got started after finding the popular site, "Badger and Blade". Over the last few years I have amassed a collection of mostly Gillettes, but also Merkur, Schick, RollsRazors, EveryReady, Gem, and a few more. My actual shavers though, are all Gillettes. My current rotation consists of a Gillette Slim adjustable, an old fat handled Gillette Tech, and an old gold plated Gillette Aristocrat.
The blades are another story. I have tried MANY different blades!! From the Gillette Super Stainless (recycled beer cans) that is sold in many Wal-Marts, to the sharpest of the bunch, Feathers. After using a full pack of each different blade (Crystals, Gillette platinums, IP's, Feathers, Sharps, Dorcos, Derby's, Gillette 7'oclocks (all three variations), and dozens of other blades which I cannot think of right now, I settled on my favorite. Astra Superior Platinums. They are nearly as sharp as a Feather, but many times smoother. Actually, the smoothness rivals that of the Gillette platinums (aka "Swedes"), and the edge retention is among the best too. All this, and you can get a box of 100 shipped to your door for $20.
For lather, I use a silvertip badger brush of my own making. The knots I order from a well known supplier to the various shaving forums, and the handles I turn using genuine Lignum Vitae. As for the soaps and creams.... That has turned into another bad acquisition disorder, as I have an entire cabinet full of them!!!!
Overall, I must say that it is a very relaxing hobby, and I get better shaves than I ever could have with modern day, multi-blade razors.
