Hello again eysha,
Well you're right about one thing, where do you start? I mean, everyone of the leading brands of camera manufacturers produce an outstanding entry level dslr, that once you've learnt out to use it properly is capable of taking brilliant photographs. So you can look at anything by either Canon, Nikon, Sony, Pentax and Olympus.
So the next thing to do is decide on a budget with which you can buy the camera and lens(es), a bag to keep them in, possibly a tripod/monopod, remote trigger cable, spare batteries and memory cards. Next you'll need to go to a shop where they'll let you have a go with a number of the entry level dslrs. See which ones fit in your hands nicely and the buttons, control dials and scroll wheels are well placed for you to use. Have a look at their menu systems and in camera guides to see which ones you find easiest to use or follow. Make sure you're happy with the weight of the camera and how balance it feels with the lens and batteries in.
Once you've decided which you like the best in terms of how they feel, then have search on the internet to see what deals there are from any of the leading reputable camera stores and then go buy it and start taking pictures.
You'll find thread after thread on this forum about choosing your first dslr, full of good advice, but the answer as to which model you should choose changes for each person. It is very much a personal decision which only you can make and you shouldn't be influenced by other photographers trying to tell you which one to buy because they find it brilliant. We all have different wants and needs. It's what is right for you that counts, everyone else's opinion counts for nothing!
Best of luck and if there's anything you're not sure of, just post your questions on here and you're sure to get the answer you're looking for.
