I'll make a vote for RGM Motors, they have the bits that enable hydraulic lock at the top and bottom of the stroke. They have the longer bushings and damper bodies that have the higher oil holes. They also can provide you with springs and stanchions. I totally agree that the Lansdowne units are far superior, but may be overkill for your riding style?
I have used Forking by Frank for my BMW R90S and my last Commando custom and was very impressed with their quality, I did find them to be pricy for the commando, and very good value for the BMW.
Do consider that the benefit of any suspension maintenance/rebuild/upgrade is greatly diminished if your ISOs are worn and/or out adjustment.
