Because I not familiar with DSLR Equipment such as different types lighting equipment and lens for what kind of scenery . So I don really dare to risk to buy it yet.
Well if you want more control over your camera, DSLR offers such opportunity. It's not all that difficult to get decent photos, but you must be willing to learn how to control and willing to move around and really take photos, try out how to aim, how to manage your exposures etc.
P&S don't give you as much control over the camera, just tons of features to make post processing easier and move controls out of the end-users by automating certain tasks such as exposure control.
If you find the risk high, you can always opt for a 2nd hand DSLR. There are a lot of people always trading their gears in the Buy&Sell section of Clubsnap forum, feel free to visit the forum. There are a lot of photography peers sharing their experiences and art works, don't hesitate to learn from them too.
