The 777 (which had a street price as low as $1500) is no longer in production, but will be replaced by a multichannel model called the XA-777ES, to be released sometime this summer. It is a front-loader (the 777, like the SCD-1, was a top-loader). The SCD-1 has been quoted as available new at around $2800 to $2900. Similarly proportional discounts appear to be available for the DV-9000ES and 333ES from sources such as J&R Music and Oade Brothers. Sony will be releasing a number of other models later this year, down to a price point of $299.
The Marantz SA-1 lists, I believe, for around $7000, and the new SA-14 for around $2800.
