Hey dude. No one can tell u what to do. Looking at ur posts, are u sure u will like photography? It's not for everyone.
Don't mean to be rude, if u can be in a situation thinking of whether to get D40 or 30D and D200, u might just as well get D40. Apparantly, u have not got the understanding for the use for a semi-pro model. And, u don need a dSLR to shoot well, don be misled by commercials and marketing stuff. Of course, if u are using a dSLR, it really does offers much more capability than normal prosumers or compacts, but have you gone to the stage where by u need that kind of gear? U may end up having a $1-2k equipment sitting there, not utilising them well; of course if u are happy of doing that, it's none of my business either.
Like what i always post, I will recommend ppl who are in the stage of "still not sure" or "newbie wanna play with cameras", to just get a good prosumer camera. Fuji has some good ones like the S9600, Sony also had some good ones. These cameras should be able to let u play with many features offered in dSLRs, at a low price and not having to be concern about maintenance too much. Furthermore, if u discovered that u really like photography, by then u would have known what kinda things u really like taking (landscape, portrait, telephoto, etc) and have at least some good knowledge technically. The S9600 should cover a good range for most things you might wanna shoot.
Also, getting a prosumer can be win-win situation as:
If u plan to get dSLR --> keep the prosumer (or sell it) for travelling usage or for other purpose. Trust me, u will not like the feeling of carrying ur dSLR gears all over the place all the time.
If u don like photography --> u'll end up with a not so expensive and more advance than compact camera camera (not to mention, u will save $).
But if you very sure u really want a dSLR and will not settle for anything less, try getting one in the B&S to start off with. D70s is also good.
