I know I don't need to tell you this, but for the benefit of others, ride quality is more of personal preference and how you set your dampening/ride height/spring rates (depending on which, if not all, are adjustable).

Asides from the fact that if on the rare instance you need to have the Silkroads rebuilt, you'll have to send them out (of the country); I've heard nothing but good reviews about them.

Jesus (the mod of cycle corner) has D2 coilovers on his 240, and asides from being stupidly cheap price-wise (as in under 700 bucks), they are of nice quality and perform well. And they're also dual height adjustable (preload and height), as well as come with camber plate/pillow ball mounts. And with 8/6 springs and the dampening set to full stiff, the ride quality wasn't that bad either.

Just another option to consider.
