I would also like to point out that on average for the year 2013 we are budgeting that each unit costs approximately 200,000 THB to run and maintain which equals approximately 5% p.a. retune on a investment of 4,000,000 THB which was the average price of purchasing your unit, Your rental retune for the year will cover the running costs including the generator.
Looking forward with most of the major items purchased I can only see Code going from strength to strength.
