I think his first solo album is quite good. The rest of it doesn't do a whole lot for me. Although to be fair, it's been ages since I've listened to About Face, so I may have to revisit it at some point. And I've yet to give Rattle That Lock a thorough listen, which I'll have to do as well. On an Island would be a good cure for insomnia, I think.

I think some of his live concerts are worth checking out. I especially like the concert movie from the About Face tour, absolutely killer version of "Short and Sweet"(with Roy Harper on co-vocals) but I don't believe it's ever been released on DVD(I've got the VHS).
