Nothing wrong with a chain drive. You can just as easily take a finger off with a belt drive as you can with a chain. A cover would be a nice addition though.
Other than that, looks like a real nice unit. I have used horizontal band saw both dry and wet. The blades last longer and cut better when wet in my opinion. Most of the ones I have used (DoAlls and Kalamazoo) the rattling of the saw band cover made more noise when cutting than anything else.
I am still looking for a nice power hacksaw. Blades are cheaper, if they break they don't become Cobra's flying around to bite you and they are accurate. They are slower but I am not running a production shop so not an issue.
