Congrats on being pregnanyt!
Here is the crib that I got for my daughter, ok well my parents got for her, along with the rails for later.

I am not sure about a toddler bed though but this is a convertable bed. I am not sure how much you are wanting to spend, this is our first child and I am sure that the next crib that we get will be just a crib as they are kinda pricey. The reason I like this is becuase it grows with your child, but if you think of the price, a crib is around 200 a toddler bed is around 200 and you know how much bigger beds are. So this option worked for our family.
Let everyone know what you decide to do.
If you do not mind getting something used you can look on ebay and craigslist or at garage sales. ( I would just replace the mattress if it comes with one) Let me know if you have other questions, I think I have a bunch of the other ones I was looking at saved on my computer.
Good luck
