Sadly this advice is a little bit out of date, as the SKX has been out of production now for a few years and the price on uses examples has risen above what one is worth (except to collectors).
The newer advice is to grab a Seiko 5*. There's a million different choices, and all the current ones come with the 4R35 or 4R36 movement, which are better than the 7S26 which was in the SKX divers.
