Which DE razors and blades are good ones, and which ones should I avoid?
You can pick up nice used Gilette's on eBay all the time in the $15-25 range. Look for the adjustable, twist-to-open models. Ask Kohai999 to point out a few good ones for you.
Otherwise, I like my Merkur Futur a lot. But, it's a pricey razor, $60-65 typically. It will, however, be a lifetime investment for you since it is so well-made. The Merkur Progress is also well-reputed and a bit less expensive; I've never tried one.
I like
www.classicshaving.com and
www.westcoastshaving.com for supplies.
Am I better off with an adjustable, or a nonadjustable?
I have never used a non-adjustable. It makes about as much sense to me as one-size-fits-all dress shirts. It takes a few shaves to get your adjustable dialed in, but, then again, you can get it dialed in. With a fixed razor, it'll either be perfect or not... most likely not.
Also, what shave soap and brushes do you recommend?
I have the matching Merkur brush for my Futur. A few hairs fell out in the first few days, but I think you have to expect that. Now, I loose one hair every eight or ten weeks. It's that solid. Properly used and cared for, this thing will easily last ten years of daily use. Again, it's sort of pricey, $80-90 to buy, but DE Shaving is the thinking man's way to shave because you have to think about the long-term savings, not the up-front cost. This is the only shaving brush I have ever used, so I have nothing to compare to. The first time I used it, though, I really felt as though I was in the proverbial lap of luxury; it's just soft and luxurious on your face. What a nice way to start the day, eh?
As for soap, my experience is limited. I had a scrap of C&E and couldn't get a good lather from it and didn't particularly care for the fregrance either. I tried Classic Shaving Soap from classicshaving.com and thought it was good, but the Fresh Lime fregrance (the only one I tried) was very sweet and artificial. I now use soap from
http://www.thegentlemensquarter.com/category.php?cid=1 and I find the lather great and the fregrances very nice too. I especially like Black Code and Lime Margareta, but that is just a personal preference thing. One nice thing about shaving soaps is that they don't generally leave a strong fregrance behind since you rinse well after your shave.
Wow! I don't know what DE Blades are $6 for 10. Feathers are about $40 for 100 (which come as ten packs for ten so you could split them between two of you). BICs are $20 for 100 (which come as ten packs of 10). Derbys are about $25 for 100 (which come as twenty packs of five).
versus about 30 bucks for 3 or 4 Fusion cartridges. I can't afford NOT to shave. Considering the Merkur Vision costs less than a top of the line electric, and doesn't need expensive batteries and blades, I think even an expensive DE razor is a huge money saver.
I like the way you think. Another thinking man.
