I picked up the travel size available at SRD, based almost exclusively on Robin's reviews. The travel size is quite affordable and while it's a small quantity, I use so little for a shave that the price is justifiable for me.

I've had good results with it so far after a few shaves. The question for me is still whether it's noticeable from jojoba, which I have been using as my preshave and is available locally. The CF stuff does have a peculiar scent, but it's faint and has been overpowered by every lather I've used thus far. It's water soluble and does not leave any oily feeling on skin or whiskers.

I have no complaints with the purchase and think it's a good preshave.
