Not to promote myself or anything, but I have a freaking sweet sample thing going on on B&B right now. But it includes razors with you already have... As to one brand: I started with Derby Extras and switched to Shark blades, mainly for the picture of the shark on the box. But they really are better blades in my opinion. Drew
I don't recommend Bull Mastiff for a new guy or the NEW head. The BM is a heavy handle and even some experienced DE shaver find it too heavy. I have a new project in the works the BM Ultra Light with a anodized aluminum handle, only problem is the whole batch has to be the same color, I'm thinking black would look sharp. Sorry to hi jack this thread but I recommend that new guys start out with a razor like the Super Speed and one of the sample packs of blades.

I started with a ball end old style open comb and derby extra. That worked great for me but, Cooncatbob has made a very good point. So use all the info everyone has given to make your choice.
