I've seen both of those sites, they've been busy on the "other" auction site. I bought one of the generic ARFs. Was not at all impressed with the quality. Parts did not fit together well, the covering started separating from the glue, firewall was not well fastened to the rest of the fuse, etc. Have you actually flown, or seen up close, the planes you suggested? I'm a little hesitant to buy unless I know they are better than the one I bought.
