The M8n ublox gps units are lower cost and can output 10hz.
Beware having the GPS within a few inches of the particle can degrade performance of the gps. Also, beware many of these do not remember their baud rate and update rate settings if their backup battery dies. I recommend sending the config messages at the default baud rate every startup to kick it back into the desired mode. If already in the desired mode the messages are ignored and cause no harm.
This has some code you can start with.
