The Roland RD88 seems overpriced if the only intended use it playing a VST piano. The FP10 and FP30 seem more than adequate (keeping in mind that only the FP30 supports continuous half-pedaling with an optional pedal, whereas FP10 supports half-pedaling, but not continuous, with an optional pedal).
Another interesting option is the Korg D1, which has Korg's top action as far as mechanics go (possibly with some small diferences). I have tried that action in other pianos and I think it's close enough to Roland's PHA-IV premium, and better than the Yamaha GH3, but that's my personal opinion, of course. The downsides are that it's slightly above the intended price, and the included pedal is only on-off. A half pedal can be purchased separately, but I don't think it's continuous. However, I don't know any piano that has a continuous damper pedal in that price range.
