MOTM Madness continues!

[Charlie T]

We got our 110 kit today, too.

Paul, it's an ace job on everything from the silkscreening, to the
documentation, to the packaging, to the delivery.  And Charlie, as you know,
thinks your designs are the best.

Thanks for everything and keep us subscribed!!

have

I'm
