Off-Site Tape Backup Storage

I am soliciting ideas on how to best implement an off-site tape backup storage plan. We have a very solid tape rotation and off-site schedule plan. However, our current off-site storage location is at home.

While this method is cost-effective, convenient and makes tape retrieval very easy, I don’t feel that it is the best option.

Do most folks use outside services to provide off-site tape backup rotation or are there other obvious methods to maintain an easy, convenient and readily available off-site rotation.

Thanks.
