I bought Garmin GPSMap 60CSx via ebay for $300 + $42 shipping, got it delivered in less than 5 days from USA to Karachi via Fedex.
But unluckily Customs held it and asked for the NOC and some complicated Procedure.. I had to go Airport thrice in 2 days, and finally got it cleared through an Agent today 
Total expenditure (including “KHANCHA”) incurred Rs.3500, while Custom Duty was only around Rs.300 The overall experience with customs was pathetic, Its my last time, I will never buy and ship anything via courier!!
Coming back to the unit, So far I’m loving it.. I have yet to read the manual thoroughly and hope to make good use of this toy
ahhh, I had to go through a similar ordeal. See my post for more details .
