If you are new to straights and you want to buy a high end razor (and it doesn't get any higher than that), go the the buy-sell-trade forum here and buy a couple of cheap (compared to zowada, anything is cheap) razors of different sizes and grinds so that you can try them all out.
Otherwise you might end upo with an 800$ razor that you don't enjoy.
By trying different things first you'll know exactly what type of razor you want to have.
