Gearbox options for Fisher Price

[2544HCRC]

AndyMark is out of the 4:1 AM0002 gearboxes again until next Tuesday. I was waiting till today to order some but they were snapped up between the time I got the email last night that they were in and this morning when I found out they were available. Now we are more than behind. What are the options for a gearbox for the Fisher Price Motor? It seems weird that nobody makes a simple gearbox like those for the CIM motors for the FP motor or the Banebot motor. I'm looking for probably 10:1 total reduction. Are there plans for gearboxes somewhere? Also we had no luck last year getting any Dewalt drill gearboxes. It seems that the local DeWalt service center went out of business and the regional one will not give out defective drills due to, their words, "liability reasons". Our machining capability is pretty much nonexistent but we can call on a shop to turn out some parts if needed and not terribly complex.
