It's a personal decision.

A disposable-feather type is less forgiving than a straight razor. The feather razors because they are more substantial have more of a straight feel to them. Really, if you intend using a straight at some point you might as well just get one to begin with. Check the classifieds and get a basic serviceable razor and a basic strop and the other stuff you can buy basic at first. Honing and stropping are just parts of the skill set you need to use a straight. If you are considering a shavette you might also consider a DE which will introduce you to the wet shave routine the same as a straight.
