I recently bought an Onix XCD-88 (MH CD25) and it's been terrific. When I bought it the guy at AV123 actually steered me away from the XCD-99 (MH 25.2) because the differences were so small as not to be worth the $250 price difference. He said the XCD-88 would be discontinued, just like the MH CD25.
Looking at the AV123 site, it looks like that has happened. The XCD-99 is the only one available, but they dropped the price from $499 to $399. You might want to call them, as I bought my XCD-88 as a B-stock, and it was never listed on their site. They might have B stock of either model available, and they give full warranty on them. Much cheaper than you can buy the Music Hall units.
