Take your time, and go with what feels right. After our first, I swore up and down and sideways that she would be an only (even sold all my baby stuff). When she was about 3, we thought about another one. Due to a number of reasons (including financial - DH was contracting and it wasn't guaranteed that we would have insurance after his 1 year contract was up), we waited and our DDs are almost 5 years apart. I had my first at 30 and my second at 35, and DH was 36 with the first and 41 with the second. Having one baby at a time has been great, and I love, love, love the age difference. I'm one of those crazy people that thinks that less than 3 years apart is too close. It just wouldn't have worked for me.
