I am also wondering this, as eBay has a lot a brands. Also, has anyone used, or heard of anyone using, or heard anything about Eurgle brand servos? I looked around the net for a while and could only find a few places that even carried them, mostly just on ebay. And they're really cheap, like $7-$13 for a 262 oz-in. Wondering if those are a complete wasted of $$ or not.
