I have had a Fiddlerman CB bow for over two years.  It has held up very well during that time.  I take private lessons now and my teacher was pleased with it when I showed it to her.  A lot of her new students have cheap wooden bows that came in a kit when they start with her, and she was happy that I had something of such good quality.

I can't speak towards the difference between CB and wood because I have never used a quality wooden bow, but that is my two cents.

The definitive answer to almost every question is -- wait for it --- it depends. One of your initial requirements was that the bow be under 100 bucks.  I have a couple of FM carbon fiber bows and they are under $100.  In that price range, I don't think you're going to find a better bow anywhere -- and I've looked.

Are they as good as a pernambuco bow? In my opinion they are not. But again, that depends on the bowing style of the person playing it and other factors.  I find the CF bow to be a pretty lively bow with a tendency to be a bit bouncy near the frog unless you pay attention. Now that's not necessarily a bad thing -- it's just a thing, and sometimes that's what you want in a bow -- again, depending on your bowing style and the type of music you are playing it may be, and often is, perfect. 

However, I tend to like my pernambuco better for most things, but again they cost more.  Starting prices for pernambuco bows are in the $300 range and go up to many thousands of dollars.  Additionally, one has to be more careful with them, they are more susceptible to changes in humidity, they can warp, if you break it you will cry real tears, and because pernambuco is an endangered wood, it would be unwise to ever take it out of the country -- and don't ever think of taking it out in the rain.  

All things considered, and based on your price requirement, I'd say go for the FM CF bow.  It's going to be vastly superior to ANY fiberglass bow and better than any wooden bow I've ever seen that costs less than $100. There are quite a few concert violinists that are playing carbon fiber bows these days and there are new converts all the time.  It is true they probably aren't the FM version -- usually Coda Bow or Jean Paul, and a lot more expensive, but CF none the less.

Ultimately, I guess, it's kind of like shaving. Some people prefer the straight razor because it's traditional, more elegant, and there is ritual surrounding each shave.  The straight razor is something you will own for a lifetime and some care was taken in choosing the right one. It has to be properly handled and cared for before and after each use.  It may have even been passed down from an ancestor. 

On the other hand, most people prefer a disposable razor which does pretty much exactly the same job, requires no care, didn't cost much and when it's used up you toss it and get another.

Good advice, Uzi.
