Initially I adapted a C-band Moteck horizon-to-horizon motor to a 1.2m offset dish that had been on one DG-380. This works a lot better and moved the remaining stability issues to the dish mount itself. I had originally used the Moteck on a lightweight 1.8m prime-focus dish, which was far more than it could handle when the winds kicked up. But it can manage the 1.2m. That motor was one of the last in-production FTA HH motors and apparently was discontinued at least a couple of years ago.
Since then I found a heavy, 1.8m Prodelin fiberglass offset that I adapted to the top-of-the-line Ajak HH180 motor, normally used for 3m and above prime-focus dishes. This dish is in my most wind-exposed position on top of the roof, and is absolutely rock solid in the worst wind storms. I use this as my main Ku dish for critical and hard-to-get feeds. I've recently put up a 2.6m prime-focus solid Birdview with a dual ortho feed. This has a similar Ku gain to the Prodelin, but isn't as stable in high winds in spite of being mounted on a 6" schedule 40 pipe. But much better than the 1.2m Moteck or my second 1.2m offset that was still on a DG-380, and has since been decommissioned.
For everyday Ku feeds I have three Wave Frontier T90 toroids covering the visible North American arc. These don't have the sensitivity of the Prodelin, Birdview or 1.2m offset, but work well enough for most feeds. With the optional wind-stabilization parts that ship with the T90s, they are completely rigid and stable in any wind storm I've experienced.
