The problem with this is that there are very few pure-bred cats out there. Your other cat was probably a mix of tabby and who knows how many other mixes in his "family tree"... know what I mean?
Also, remember that cats are known to have unique "personalities", so don't assume that one "just like" your other one will be the same.
I would instead look for a cat that has a "personality" like your old one rather than looking for one that looks like it or is the same (or close) breed.
Here is what looks like a very comprehensive site showing and describing the various breeds:

Hope this helps!
