Don't be afraid of the Nicholson 49 and 50 that are made in Brazil. That's what I use and I like them a lot. No, they're not exactly the same quality as when made in the USA, but they're close enough, and a lot better than any rasp you'll find in a hardware or dept store. I wouldn't want to make bows without them.
The next jump up on the quality scale will get you into the likes of Liogier, Auriou and such which are over $100 each. Great tools I'm sure, but I just can't justify their cost... yet, though I'd like to treat myself to one someday.
