The CW Keyer
I finally decided on using the PK-4 IC from Jackson Harbor Press my decision was based on the number of features incorporated into their device
Arduino morse keyer
using a paddle to operate in morse code is very convenient. but paddles don't create dots and dashes on their own, so you need some electronics called a keyer
CW Keyer with Arduino Nano
the keyer is suitable as a standalone keyer or for keying the radio via the usb port from a connected computer and your favoured contest logging software or for daily operation

I have used this keyer for several QSOs and it works well enough
