any common/cheap stepper motors smaller than the 28 byj-48?

[engineheat]

Hello.

I've been using the 28 BYJ-48 for a project and while it's quiet and offers the torque I need. The size/weight is a bit much for the space available. Does anyone know of any common/mass produced stepper motors that are tad smaller than the 28 byj-48 but still offers torque within the same order of magnitude? Something like the "24 byj-48" (if exisits).

Thanks
