I believe there's a tradeoff here so far as learning OO goes. Using a combination of MG, Transfer and Coldspring for instance will give you a good example to learn from. Once you see how things are done using the frameworks, you may be in a better position to architect something on your own. Speaking from experience, it can take a *very* long time to put all the pieces together on your own, years. And if you need to be productive in that time, well, that's where I'd recommend that someone new to this jump into what seems like the deep end and use these frameworks for awhile. That said, you need to know at least the basics of using components to use the frameworks.
Attempting to build something without the frameworks may seem like a shallower learning curve, but what you may find down the road, once you get your basic business object, DAO and/or gateway working is that you don't know how to progress from there. You'll be in deep water without knowing it. Your applications take you longer to build, it seems like you've learned something, but now what? If that's as far as we get, from a productivity standpoint, we should just stay with procedural code. The frameworks give us the space to be apprentices of OO, which is good, rather than taking too large a step, attempting to be a master of OO in too short a time, and usually, for most of us, without any personal guidance. They also allow us to focus on our client's needs, rather than get lost in abstract architectural questions. I find Transfer in particular allows me to be much more productive than I would be using procedural code. If I were to guide someone, I'd suggest that they dabble in attempting to build a simple application on their own, just to get the hang of using CFC's in an object oriented manner. But just dabble. Jump into using the frameworks as soon as you can, even if it seems like the deep end. It will probably save you from developing a code base that you need to rebuild from scratch several times over! If you are staking your finances on such a code base, I think you'll be much better off using the frameworks rather than on your own.
