First off, laser printing and DTG are very different. Also, the equipment for DTG is much more expensive.
There are some who don't have problems with their DTG printer. Others have many problems. That being said, I was highly impressed with the Brother GTX when I saw it in action at a recent expo and it would be THE printer that I would like to have if money were no object. $22,000. I would recommend that you do not buy a DTG printer with no warranty because the repairs are quite expensive.
I don't think that you can print signs/banners with the DTG printer. Unless those signs/banners are 100% (or mostly) cotton. So it's best for t-shirts, caps, shoes, etc.
As for printing onto black, you are not listing screen printing as an option. Maybe you don't have the room. If you have room for a screen printing press maybe you could consider that. Or you could have somebody print plastisol transfers for you.
