Free native TCElectronics M3 reverb (VST/AU)

[Timo]

Single "Hall" algorithm, with pre-delay (>100ms), decay (>10secs), colour and mix (%) controls.

Doesn't sound too bad either, nice for ambient style reverb, supplementing other reverbs.

I like free stuff.. especially free VSTs! :) This one looks good...
