We have a couple of them. They work really well and are very safe. However, like any other specialty device, they are quite expensive. We used less expensive winch-operated stackers successfully for years before purchasing a Serverlift.

PS- I saw you recommended this product in another thread. I hope you are sincere and not just shilling for the company...
Hey I visited you link. It was very best one.The SL500 Server seems really useful as it has 24 inch slim frame fitting on 4 oversized swiveling castors.
