I recently purchased a Amzdeal GSM GPRS GPS Tracker from a dealer on Amazon.
This tracker sends a text with its current GPS coordinates when you call it. You can use the coordinates in a smartphone app such as Polaris Navigation which will help you walk to the coordinates. Mine also sends a text with a link that you can open in google maps showing a satellite image with the location marked. So one limitation for using this device is the availability of cell service at the launch site.
I've flown this device twice and it worked as designed. Luckily I did not need to use it to find the rocket but the coordinates returned by the device were accurate.
I bought this device on Amazon for under $30, but after much looking I can't find my records of the purchase. I can say that it did come from China. Searching on Amazon you can find it for around $22.
The GPS Tracker requires a SIM card from a GSM cell phone service provider, I used AT&T. Their goPHone sim card with $15 prepaid service cost $25. Each text costs 20 cents. The $15 prepaid service is good for thirty days, you then have 59 days after the prepaid service expires, or is used up, to buy more prepaid service without voiding your SIM/phone number. If you go past the 59 days without purchasing more time, you would have to purchase another SIM card.
The GPS package came with the Tracker, two batteries, a charger, an extra battery cover, instruction manual, mini-CD
Below is a google map from one of the texts sent by the tracker. The green arrow is the tracker location the other markings I added for clarification.
