Search and then pick US only for US suppliers.? They usually charge more. But you will get them in a few day or week.
Order 1 from them, 5 from China.

Has anyone developed a color display for the VFO showing S-meter, modes, PO, etc?\
for the BITX projects?

Re: Raduino
Not really. I've had good luck with all so far, so I tend to buy the least expensive. Lately, I'm using the Arduino Mega 2560 Pro Mini and there aren't too many of them yet. (See: ebay?162264493523).

Re: Bitx40 another Raduino(?) problem

I2C has several speed modes.? I think as slow as 240Khz or thereabouts. 400 is the popular fast speed?
Here is a good starting place for looking at I2c.

I'm not sure. The I2C interface can handle quite a few devices and the board does have the pullup resistors in place. However, given what the Si5351 is busy doing, I wonder how much bus traffic the
