The Dovo Stainless Steel Handled Shavette is a great straight razor that won't break the bank. The blades which are disposable allow for ease of replacement without the need to sharpen. The razor comes with 1 red and 1 black blade holder insert.
The Red Holder uses standard double edge blades that you split in two
The Black Holder uses a specialty blade that is longer but very similar to the traditional double edge blade.
