I don't think they make the 500W Trend any more, but your post set me digging:

Trend T4 (800W)
Sound pressure Lpa 91.1 dB(A)
Sound power Lwa 104.1 dB(A)

Kress 800FME (800W)
Sound pressure Lpa 77 dB (A)
Sound power Lwa 88 dB (A)

I'm not sure which measurement is used to plan for ear defenders (80dB advisory, 85dB compulsory).

The Kress seems about 40% more expensive though based on list price... I might ask the neighbours if they'd be willing to stump up the difference!! :lol:
