Wondering if anyone has experience with a cheap fret crowning tool. For example, this one on eBay:

My expectation is that it will be a bit crap compared to the StewMac version, but will it do the job?

It's about 10% of the price of the StewMac file for the same purpose. So as much as I prefer to buy quality tools, I can't ignore the price difference:

If anyone has one of these cheap ones and can verify if it works (or not) that would be helpful.

(I can also just use one of my existing flat files to do the crowning, but if a $5 tool will make my job much easier, hey why not?)
