Ignore that website. It looks like an affiliate advertising website. Linking to these kind of website here does not go well with our forum

Back to your question. If you are not in a hurry I would wait for the SH5000. The Maxpeak we sell has datafile for North America only. Any other regions will require a datafile from the mfg at an extra cost of up to $75. You will not be able to modify or create your own datafile.
With the SatHawk 5000 you will be able to modify or create your own datafile for any KU/C band satellite in the world. No extra cost for that.
