Hello trance_mama,
The D300 and the 450D are in two totally different classes: the 450D is an inexpensive, compact entry-level DSLR that is capable of taking very good images, whereas the D300 is a high-quality prosumer DSLR with a rugged weather-resistant build and features/enhancements that make it fitting for a wide range of "serious" photography.
So, if you want inexpensive, compact, but limited in use and abuse, the 450D is very nice, but if you want a camera that is high-performance and will allow you to stretch your abilities and can handle less-than-favorable outdoor conditions, you would be better served with the D300 (or, alternatively, for a lower price the Canon 40D; it does not, however, have the weather-resistant body).
If at all possible, I'd suggest you find a local retailer who carries both bodies and handle the 450D before buying it. Many people find it too small and "cheap", whereas others really prefer it because it's so compact. But, like I said, both cameras can capture great images -- the D300 does, though, offer more high ISO range for low light shooting.
Have fun,
Tony
