I have been using FarmTrack by Farmworks for my field records. It integrates with their Farm Funds module for accounting, but I haven't gone that far yet. I use their TracMate software with my Compaq Pocket PC and it works well. Their multi-layer mapping and livestock modules also integrate into it. If you are wanting an integrated system for field records, accounting, GPS, etc. it looks good. I have been VERY pleased with the company and support. I'm just not sure how much time I am willing to put into it. Go to www.farmworks.com and look around. Drop me a line at n9gik@arrl.net if I can help.
