An updated DA/RAM/etc. with a Phoenix, HPR, and DBE is basically a Kraken (yes, there were additional flow improvements made possible with "from the ground up design). So, if you had a thing for "shiny stuff", a pimped old DH would be the thing. Otherwise, yeah, the Kraken is really a good choice.
Tht "Series 1" that is at The Scuba Museum would be challenging at best to make DIN (same one I have). Again, it works with my pro-valves, so you just need tome yoke plugs if your DIN is not 300 BAR......
