I have an F. Winkler bow as well. I paid $280 for it back in 2007. It's been a good bow. 138 grams. It's bright and clear, has a nice sautile stroke, but not much in the way of grab, consistency or power.
A luthier here in CT said he's seen several violin bows by that maker (workshop?) that are "good student level bows".
I've liked it for a while, but it's caused some technical issues that I was blaming on technique all along. It still outplays any bow in the $2-500 range.
I just picked up a D. Muniz - Brazil - that blows the Winkler out of the water in terms of volume, bounce, control and tone. Doesn't do sautille as well, though. It's alway a tradeoff at that price point. Great buy, though. Haven't looked back.
