I just found out about geocaching and i instantly became hooked. I am interested in either purchasing a handheld GPS(new or used) or in some way using my brothers old handspring PDA. I have seen some GPR recievers that dont have screens or anything that you just plug into a PDA to view your results. I am wondering if many people do this, and if so which reciever to get and with which software. If it turns out i cannot this PDA, I was wondering which GPS unitsthe more experienced people would recomend. I also have a limited supply of money, probably only around 150 dollars. Thank you very much for all your input.
