In General i would advise for newbies less expensive but quality blade.
it will be used honed and in classified you could find for 50 or less.
You can try shave ready blade and shave with it for a months to figure it out do you like to use straight razor or not?
Do you have enough patience to learn how to use straight razor etc.
Newbies have a great chance to drop the blade ,hit sink so on.
if anything happens not big deal you bought 50.00 and you find out what is next step.
You like straight razor go head spend more and buy brand new razor better quality etc.
if i were you i would read wiki first and spend some time to practice stropping etc.
then choose one blade from classified and move on.
just my 0.2 cent.
hope helps.
