Generally, I don't shave in the bush.  When I travel, I often opt for a Mach 3 - I shave once in the shower and do a second pass with shave oil in front of a mirror; a Mach 3 and spare blades, shave oil, sm. chip of alum block, and small mirror, and $12 US Brawn Travel Shaver (2 AAs) are in my dop kit for short-term use while traveling.
At home wet-shave with a  
Merkur Slant-Bar  (long), a Merkur Silver-tip Badger Brush (stainless steel) and  Col. Conk soap ($1.50 US), and finish with an alum block and then a dab of Nivea for Men Sensitive After Shave Extra Soothing Balm. 
Shaving with a safety razor takes a bit of time, but its a great shave - especially for guys with heavy, coarse beard growth.
I started with a regular Merkur HD (long) before moving to the Slant-bar razor.  I buy blades in bulk - I like the platinum Merkur and Feathers and get about 5 or 6 good shaves from a single blade.
Sometimes you can find inexpensive, used saftey-razors online.
As mentioned by another member, an  
Alum Block  is an inexpensive anti-bacterial deodorant, and is also a great after-shave that closes pores and stops minor knicks from bleeding.  I use  
My Nik is Sealed  for nicks that need it. 
There are lots of online recipes for crafting your own shaving soap: 
http://candleandsoap.about.com/od/soaprecipes/a/cpshavingrecipe.htmI've never tried making it myself, but shaving soap is usually a good quality soap with about 2 tsp. of Bentonite (or other clay: Kaolin, Rhassoul or Fuller's Earth) mixed in for every pound of soap in the batch. 
There are also many of safety razor and straight razor tutorials online: 
http://www.youtube.com/user/mantic59Best shave I ever got was from a Vietnamese barber with a straight razor and hot towel.  Freaked me out when he shaved my whole face.  His wife offered to thread my eyebrows but I passed - both good barter skills though.
