Looking for best DAS today (tape backup?)

I am an IT consultant in Charleston, SC we have several small businesses that we support and offer assistance to.

The current problem with almost every business is which tape backup hardware solution should we choose?

Travan – YUK
DDS4 – just not enought space
LTO – way too expensive for small sites

So I am looking for solutions if you have a thought please let me know. Thanks in advance 😉
