Others in the DPS range include the DPS-M7 Modulator, DPS-D7 Delay and the DPS-V77 which was a powerful multi-effects unit with digital i/o (albeit on a non-standard proprietary connector) combining the best effects from the DPS-*7 range. There was also the SRE-777 Sampling Reverb which used sampled impulse responses of top concert halls and acoustic spaces; it was incredibly expensive.
I also use their TCD-D7 portable DAT recorder, which went to Africa with me and recorded music and various creatures out in the bush.
As well as two other cheaper effects units (DPS-V55 and HR-MP5), Sony also made the following units, none of which I own or have ever used - I just list them here for completeness: (their website links broke though)
