probably those receivers just are that cheap today. The slightly more luxurious
"Made in France" version at Drotek costs 35 Euros.

The NEOs are a little cheaper than the bigger LEA receiver modules as they only
have a ROM and no flash memory. That means that you can not update the software
and an extra EEPROM is needed to store configuration data (the HK/Drotek boards
do have the EEPROM, or you use gps_ubx_ucenter.xml). On the other side the data
sheet guarantees you a 5Hz position update rate with a ROM-based receiver (and
not only 2Hz as the LEAs).

Some Lisa/S samples use a u-blox MAX-7 receiver. In the past new generation
u-blox receivers were 1:1 replacements, maybe you have to look in the u-blox
center if there are some binary configuration messages changed.

The modules should be compatible. Be careful with the simple dipole antenna.
