I'd say it depends on what you buy from them. If it's a proprietary piece (meaning they make it themselves) it'll likely be lower quality. They do resell a lot of name brand parts today, so the quality is equal to a lot of other places since it's the same stuff. If I had your concerns I'd call them and ask where the parts come from. If the spindles are Magnum, then you know the frame of reference. If they hem and haw, dance around the subject, then you gotta wonder if saving a few bucks is worth it.
