“I have bought systems and obtained valuable advice from David Graves at SourceTech Systems for many years.  He has provided prompt delivery and excellent support each time.  I buy used equipment to use in my business so sometimes issues arise and he is quick to provide support and replacement equipment whenever needed.  It has been a pleasure to work with SourceTech all these years”
