tanabe dd is discontinued, new version is SEVEN.
FYI--from our experience the most important part for a coilover is the ability to be rebuild and also at a reasonable cost.
on a street car, most coilover won't last over 2 years(depend on driving style and also road condition of where you live).
our last advice is that you get what you paid for, so don't expect $1,000 coilver to be as good as $2,000 ones.
the key is to find what you "need" 90%+ of people will never need D1 or Racing level coilovers.
good luck,

sam
ps..NEVER buy used coilovers.
