I checked over at flea bay, 966 draw knives were listed, looks like $20 will get you one in pretty good shape.
The thing about draw knives is they come in a bunch of sizes, shapes and handle configurations.
I like a heavy, straight blade, with the handles on the same plane as the blade, others may prefer a curved blade.
If you buy one of the auction site, be sure it is the kind you like before you pick one out.
