MOTM

Here's an alternate source if you need knobs for MOTM-compatible 
projects. 

Radio Shack has "274-416 A" knobs at 4 for $3.00. I got them at a 
local store, but it looks like they have them listed on their web 
site as 274-416's. 

They are nearly indistinguishable from the knobs that come with MOTM 
kits. At 75 cents each, they're a dollar less than the Alco knobs, 
and you don't have to buy 30 at a time. 

There are slight differences. The Radio Shack knobs use a screwdriver 
to lock on, instead of a hex key. 

Hope this helps those of you that need to save a few bucks for more 
modules!
