Newbie question: NAC 282 and NAP 300DR direct connection

Would be interested in peoples view of a SC ( non DR) over one or even two HCDRs.

non-DR Supercap vs HiCaps with NAC 282

There are similar threads I know, as well as 1 vs 2 HICAPS on a NAC 282, but when I got the NAC 282 I envisaged a Supercap DR next, then a move to NAC 252. Would a reasonably priced (and how much?) secondhand non-DR Supercap beat 2 olive HICAPs? I believe a Supecap can also be upgraded to DR specs.
