In my mind, one of the biggest advantages of a take-down bow is that you can replace the parts if there is a problem, or if they no longer serve your purposes (i.e. draw weight change, etc.).
I don't disagree with the used bow suggestion, just be careful buying on the auction site. Sometimes the sellers don't know anything about archery and may inadvertantly sell you a junk bow (twisted limbs, etc.). I learned this lesson the hard way.
I bought a Samick Sage for my daughter, and it's a good value. I had a friend that had a Martin Jaguar, and it also seemed a decent bow. I prefer the Sage over the Jaguar, but that's just because I prefer the wooden riser over the metal one. You may like the Jag better, if you're used to a compound, just because it's closer to the feel that you're used to.
I'd suggest trying before buying if that's at all possible.
Good luck to you in your decision, and let us know what you decide. And Welcome to Tradgang!
