Here follow a few useful links that will bring you to websites where you can check out different breeds that would suit your needs best. Remember, your new pet doesn't need to be an exact replica unless you really want it to.
If your home situation has changed, you can pick a different breed than you had before.
Do you wish a quieter animal, an enthusiastic one, big small, see what suits you and better yet, what would suit your pet's character best. Did the big lug always try to crawl in your lap? Did the little darling always jump when bigger animals drew near?
All important factors, if you have the time to make your choice.
