I'm not familiar with the specific scope, and that may indicate it didn't sell well, which may indicate something of its quality--but that's guessing.
When you say it has jitters, have you let it cool down to ambient temperatures? Are you sure the night air is stable? Before giving up on it, be sure it's had an hour to cool down after dark. My 10-inch SCT sometimes doesn't give good images for the first 20 minutes or longer--the focus keeps changing as it cools. Try the cooling on several different nights to be sure you have at least one with steady seeing. And be sure you're not looking at stars near the horizon--pick something that's fairly high. And if none of that works, consider how much the cost of a new SCT has come down--for example, Meade's new LX 10, LX 90, or LXD55 scopes, or similar models from Celestron. Then weigh your time and money against the costs of a new scope.
