I've played the violin for around 5 years now. If you're willing to practice a lot, learning to play the violin won't be that hard for you. I bought my instrument when I started for around $500. Decent sounding instruments will cost you about that much. If you play the piano, like I did, starting to learn the violin will be really easy for a while because you can sight read better than others can. As for pointers, just go find yourself a good teacher. If you have a good teacher, you'll be able to get you going fairly easily.
