Thanks to all that have answered, as usual very good advices.

I am puzzled about what to do, still the total cost of it for a OXCO + 
GPS(unit with antenna) + control mcu is 67usd, I doubt I could find 
anything like this for a cheaper price new.

Only cheap alternative could be this one(already discussed here one year 


Would this allow me to play as the "standard" ThunderBolt using the same 
software? Any preferred model among
63090/73090/65256 "models"?

PS: Still I like the idea of the kit...the trimble would require PSU, 
antenna, boxing and no fancy display...
