Hello there i need some suggestions on gps,i was using my cell phone to check my boats speed but i think its time to get something smaller and to be safe in case of something bad happens to my boat..I see many people using the garmin 201 but i cant find it somewhere that is shipped to Gr (im looking for a used or in the price range of 50-60 eu) i see the Skyrc gps as an alternative that costs only 50 eu with free shipping from ebay :) im wondering thow is that gps any good?Any people that use it here have some thoughts if its worth getting it?Any other gps on that price range that you would suggest?

Thanks in advance Stratos
