A typical pattern airplane fromthe 60's forwardwould not makea good 2nd airplane, but there are what I'll call pattern-like or pattern capable airplanes that would work nicely. Probably the best one that comes to mind is the Carl Golberg Models Tiger 2. It's a kit, but don't let that put you off. It builds easily, and is a docile, yet aerobatics capable model. Easy to afford too.
