Shiny discs are available today. Players are available today. The real question is whether there are recordings that are best demonstrated in the SACD format, with little or no possibility of it becoming available in an alternate one in the forseable future, that are important enough to you to spend the money obtaining & playing today?
Regarding players, I never liked the early Oppos. If that's all you're willing to invest, I'd say "pass" on the SACD's. The Sony 5400 is probably the least expensive SACD player I've heard that satisfies. Haven't heard the latest Oppos though.
Also, if using multiple sources - computer, vinyl, SACD (analog-out) is part of the equation, you'll still need switching capability. Still have that Skipjack, Vincent? Get thee to a modder-y, my friend! For those extremely rare instances where the hi-res versions are available on both SACD and DVD-A. Still, your ears are better than mine, D.
