If I were in Europe I would absolutely consider DTD since it will be much cheaper than an American brand like Halcyon.
I imported a DTD backplate from Gidive Store out of curiosity. It has extra slots to attach weight pockets directly to it for single tank diving, which was an interesting feature. Build quality is okay, not quite as shiny as Halcyon but no sharp edges or issues. For what it's worth I'm pretty sure Subgravity resells some of DTD's products in the US under their brand, at the very least they share the same OEM.
