There really is nothing worse than a poorly handling double gun. There are those who say "good enough for me", but really, they aren't. There is just no good reason to own a badly made, poor handling, or strangely configured double gun when there are very good used guns or semis available that do handle well. The whole idea that cheap guns are really 'hidden gems' is simply not true. There is a reason that they are so much less expensive. And the reasons are almost always: poor fit and finish, poor handling, poorly made, soft inner parts, or overall low quality with bad barrel regulation, non-concentric chokes, or wobbly ribs. There is no good reason to own such a gun. Better a well worn "Charles Daly" Miroku, an older Citori, an old Verona, a Lanber (if one can find one) or a worn Fox B, for example, than some pot metal, chemical burn, mystery wood thing with poor barrel regulation and the handling characteristics of a step ladder.
Take the Baikal, as suggested above. They are tanks. For school/club guns, they are probably a great idea. They will handle a great deal of abuse because they are built like People's Revolutionary Tractor No. 10 for Third Five Year Plan Fulfillment, and, since nobody will ever get any better shooting one, they will keep the school/club/etc., in students forever. They are strong, but they handle poorly.
If a decent used double isn't in reach, then a good used semi should be. A cheap double will never be a joy.
