Unlike with basses, or wood bows, carbon bows ARE like BGs... there is no sample variation worth mentioning, so you can meaningfully talk about brands. And yes, most of them are worth the money.
There are four brands I can think of, Carbow, Upton, David Gage and Coda. Gage and Coda come out of the same factory and process, but have different specifications... understandably they're fairly similar. My own bow is a Gage, I liked the Coda bows too, and some of those are slightly cheaper. For the price, I was very impressed with the one Upton carbon I've had a go with (but don't ever get a fiberglass Upton bow, stick to the carbon). I've never played a Carbow.
Recommendation to a beginner: get the carbon Upton, it's a very good bow for the money, and you can safely mail order it and know what you're getting.
As for the basses, you have a problem: it is impossible to mail order a bass unless someone you trust who works for the supplier has tried out the bass in the warehouse and thinks it's OK. But the commercial folks on here aren't allowed to volunteer to do that, 'cause they'll get banned from this site and may even get fired for that, and you're not allowed to meet up with folks on the internet. Well, you just have to explain to your folks that this issue is worth an exception, otherwise you'll very likely waste a few thousand of their money... that should get their attention. Then get them to have a chat to whoever is nearby... it'll then be their call if they trust these people.
