And you can buy a refurbished laptop for a couple hunny from dealers that offer warranties. I bought a used Dell i5 from MacMall for $300 - I needed one with a built-in ethernet port to program different devices. Works great. I also use it on the road / hotels with Unitrunker and DSD+.
To make sure I give the proper advice, what system is giving you issues, and approximately where do you live - a nearby intersection would work. That data can help me plot system transmit sites wrt to your location.
