Perhaps I'm confused but, a quick comparison between DGX and DTD for a comparable set up
DTD: 465 Euros, including VAT
DGX: $350 converts to $317 Euros. Add 19% VAT and you're at 376 Euros, including VAT
VAT never comes alone. But this set up (dgx) seems really affordable and might be worth it! The OP might find it interesting!
@Marie13 I think the dive rite are fairly expensive compared to the dtd
