You can get very cheap keychain gps devices (not loggers) which will interface with a smartphone, and free software for the smartphone to do the logging. Or you may want a standalone GPS logger without a screen, or a fully blown Personal Navigation Device with a screen, maps, etc. I know some people insist a screen is a must, but I get on ok with a cheap GPS logger with no screen. I use a notepad (or occasionally a camera) to record the details of my waypoints. Yes, it does mean you cannot see whether you have a good constellation of satellites, but I almost never get home to find the trace is unusable. I use the iBlue 747A+, which in the UK you can get on ebay for £25 - £30, but I have no idea of availability or price in Bangladesh! I would personally recommend this device to anyone who wants a GPS logger of this sort. I find it reliable and easy to use*, it has a large memory and excellent battery life. There is also an excellent unofficial free desktop (and mobile) application available (BT747) for managing the device (or other devices with the same chipset), downloading tracks and saving to OSM-compatible gpx files. I have read the chipset is not well calibrated for walking, but I usually find my walking traces usable, if not as visually appealing as my cycling traces. But I have not tried any other devices.
