Looking for gearbox

I’m looking for a gearbox with a 1/2" hex output. Preferably compact / light that can be used with a mini CIM. All the ones I could find, like the Versaplanetary or Andymark Spinbox, are out of stock and I cannot find any that fits what I need.

What ratio?

Preferably close to 1:1, but it does not have to be.

Are you able to use a 8 mm to hex adapter?

Would an andymark cimple box work?

If you want 1:1, will this work? http://www.andymark.com/product-p/am-0588.htm

West Coast Products has them in stock. Probably not for long though.

If you go to http://findrobotparts.com/gearboxes you will be able to find almost every gearbox option from all FIRST vendors. It will let you filter by hex, Mini CIM, and ratio to narrow down what you are looking for.
