Welcome to B&B, definitely take some time to make an entry in the Hall of Fame if you haven't already.
Definitely check out the "Vendors Stores" section of the site for some pointers to online vendors. The "Shopping and Deals" section will also have some pointers. My favorites are West Coast Shaving, Italian Barber, and Maggard Razors. They are all upstanding vendors of quality gear. I also get stuff from Amazon and eBay.
Each of the various forums on this site will have all sorts of reviews and recommendations for gear. You might want to start with the "Shave Clinic & Newbie Check-in" section. There is also a dedicated straight razor section that has tons of good information. Spend some time reading and then try a few things out.
Welcome and good luck.
