Been using Groundskeepers Pro for the last 1 1/2 - 2 years and have not had any problems that weren't easily fixed with a phone call to Adkad. They have been giving free updates, but after the newest 5.0 version, there will now be a $20 update fee ... basically due to some changes that have been neccessary from the programmer aspect as well as having to incoperate anti-piracy features. It still beats the update and upgrade fees of some of the other programs. In the time I have been using it they have been great as far as Tech support and service, which has and is still currently free, and have been adding and improving to the program overall. If anyone is looking for an affordable program that covers all the basics as well as having a few more advanced features and some bells and whistles, take a look at it ... they have been great to me and I am very happy that I chose their program.
