I think you're explaining your reasoning as well as any of us could. Really, it's one of those things that needs no explanation to someone who understands.
I like the sleek lines of a one piece and don't think anyone can really do a decent job of keeping house without one, but a takedown is much more handy and versatile. You can take it apart and stuff it in a suitcase if you need to. You can buy extra limbs in different draw weights for target shooting, small game, deer, or bigger game. They generally have a heftier riser section than a one piece, which helps stability and accuracy.
For a quality bow at a reasonable price,
ChekMate Hunter or Hunter II. Hands down. Other great takedown bows, but pricier, are made by Bob Lee, Mike Palmer, Great Plains, Brackenbury, Black Widow of course (but the money![:-])... There are so many good bowyers out there that it's practically impossible to list them all. Frankly, for the prices Martin and Bear are asking for their mass produced bows, you can get a custom for about the same cash. Especially with ChekMate.
Be sure to keep an eye on the classifieds and Ebay too. A lot of recurve shooters are worse than compounders when it comes to changing bows and you can often get a lightly used bow for a substantial discount.
