Help Figuring Out Where to Buy an Oboe!

Hi, I'm a high school oboist and have been playing around 4-ish years who has recently been looking to try and buy my own oboe. Currently I'm borrowing one from my school, but none of the oboes they have are any good so I wanted to purchase my own. I've also recently gotten into a few higher level groups so I really want to make sure I have an instrument that will actually cooperate with me, not hold me back as a player, and will last me through high school and maybe some of college. I've been looking into different brands and models and know generally which brands to look for and which to avoid. Since I want to see and test the instrument first I wanted to avoid buying from places like ebay, but I'm kind of clueless on where to search. Do I go to local music stores to see if they have any oboes, do I try and look on things like craigslist or facebook marketplace, or is there other options? I've never bought any sort of wind instrument before, so I really don't know where to look. Thanks!
