Welcome, Kyo. It depends a lot on your budget and how committed you are to really sticking with violin. When I started playing again after about 20 years away, I bought a very inexpensive (less than $60) model from the internet. It didn't take long to "outgrow" it, but it served its purpose of getting me started again and making me realize I really did want to play again. The cheap violin did require a certain degree of "tinkering" to keep it in tune. If you budget is a little higher (but still under $200), you could check out some of the Cecilio models offered in fiddlershop.com. From what I have seen and heard, Cecilio appears to have decent options within that price range.
Depending on your local options, you may want to rent a violin for a while to make sure you like playing it before you commit to purchasing one. In my area, you typically pay about $25-30 for a month of rental, with an initial set-up fee equal to a month's rent. Each month you accrue some equity towards an eventual purchase if you want to buy the rental violin (or another violin sold by that shop). The rental violins should be decent (the ones in local shops typically retail in the $400-600 range) and would not require as much attention to keep them in tune, so they could be a very good option to get you started.
Aside from the violin itself (purchase or rental), the next most important "accessories" are probably a good shoulder rest and an electronic tuner.
I'm also a flute player learning violin. Ability to read music is a big advantage as there's more than enough to learn about technique on the violin. I'm sure you'll enjoy it though - I find the sound is a great contrast to the purity of the flute tone and more versatile (once you get past the cat strangling stage that is). I don't know if you remember what it was like getting the first tone on the flute, but the violin is a bit like that - only ten times worse!
Can't really advise on instruments, but if I was in the US I'd go to Fiddlershop. All the satisfied customers on here are proof of the quality of the instruments and service.
