It might depend on the size of the tape collection you have and how important it is to you to preserve it and have access to it.
If these are important issues with you, the Sony RH1 is THE answer. You can't get out of the real time transfer, tape to disk, but then it's zip...disc to hard drive.
If you have created a database as you went you suddenly have instant access to thousands of tracks. Ones that you knew you had but took a couple of days searching for or perhaps you never did find them.
Best buy I ever got.
