I've found a few razors on ebay that are fairly cheap and ending soon. Any good? I mean obviously they won't be that great, but will I get a good shave out of them without having to sharpen them too often?

Crowing Rooster 9 3/4 " Straight Razor Black/White Swirl 20700- zix | eBay

B&B TITANIUM STRAIGHT RAZOR RAINBOW GREEN | eBay

SMITH &WESSON FOLDING STRAIGHT RAZOR | eBay

New Straight Razor,Giesen & Forsthoff,Solingen, Germany, 5/8 #150 | eBay

Which one would you get/anything bad with either of them? Not sure if I'd like to spend 60 bucks on a razor, but if I have to to get a nice shave I will.
