Unitrends as a backup solution?

Hello all, We're sick and tired of Backup Exec 12 (you read that right 12, not 2012). It fails constantly, whether or not it backs up "successfully," takes forever to backup (we have LTO tape backups), and can be an utter pain in the ass to recover even small things like individual emails or files. I don't think our LTO tapeloader has much time left, either. I've been evaluating many products (Appassure, eVault, Unitrends, Veeam, and a couple others). Does anyone have any experience with Unitrends? I've been doing web conferences, one-on-one with their engineers showing off their product, calls with their supplier and one client who switched from tape to Unitrends and it sounds like a really great product. I've been looking online for reviews on forums and Spiceworks, and so far everyone's made it out to be the greatest thing around (especially Spiceworks forums). I'm wondering if anyone here has experience with Unitrends. The quote I got was a little high, but within our budget for a new backup solution. Their hosted cloud solution sounds really great, too. So, /r/sysadmin, what are your thoughts on this product?
