I haven't had any experience with any of those companies... I would have looked at the Waco's ( since I'm not into high wing aircraft ) but when I searched on their website for the Waco's, it came up with 7 variations. Perhaps a link to each model you are considering would make it easier on others that may want to give their 2 cents on them ... I will likely add at least the Manzano website to my list of hobby shops and perhaps the others once I've got time to browse a bit more.
