When I finally decided to start learning I just got the first and cheapest violin I could find.. which was from ebay for about £30 (including bow and case).. it says Bentley inside, but I have no idea about brands, and judging from the price it's prob not a great make, but I love it.
My teacher says it's alright for a beginner (although she did make me change the strings), and I figure that I should buy a better one when I have more of an appreciation for the sounds. I don't think it should matter that much if your violin doesn't sound brilliant to begin with, just as long as you can get the basics down.
Good luck anyway
