To answer your question, you will need to provide some more info. What is your recording set-up and what type of connection do you want to use.
If you need an S/PDIF connection then the Lexicons are a good choice. If you would be happy with a reverb that runs through the Aux send and returns on a mixing board, you would have a lot more options.
Also, do you really want just a reverb or do you need delay as well?
