Info from a recent ebay seller of a SPK-TRX: For the HI8 Sony TR705 camcorder and CCD-TR705E, CCD-TR505E, CCD-TR305E, CCD-TR105E, CCD-TR75E, CCD-TR55E and CCD-TR45E.

hey i have just got one off ebay and my sony digital handycam fits with a little bit of help

Have you found out? I have an old CCD-TR3000E and want to know if this is compatable with a SPK-TRX. My accessories book tells me that the suitable pack ia a SPK-TRB.
