There is a variety of what can be construed as a "scraper". Other than the flat metal designs sold as "scrapers", other tooling can be used that you may already have.
In addition to the commonly known variety, I use jointer and planer knives as scrapers. The 1/8" bar stock will seat nicely in a saw kerf of wood that you can make as a handle.
Chisels properly sharpened can be used bevel up and the effective working angle will be evident when you feel it getting a bite.
Scrapers are also available in what are called shavehooks , which because of their working angle are very effective and comfortable.
Other types that are easy to use are handled scrapers which allow control. There are holders like this one that make for a more comfortable grip on a plain scraper.
Once you get into using a scraper, you'll wonder how you ever did without them.

I love to make things do double duty (i.e. cheap). 
I am looking forward to my next free shoptime to try this out (assuming I ever finish renovating our bathroom that is!)
