I did not go to the show this year. I did last year. I have had 3 PG machines. After this one 800 hours thus far....I am leaning towards a Z. Not only do you have to think of how the machines operate but to me a huge deal breaker is:1. Service 2. parts. 3. return my call. PG compnay is poor with this. How does the Lt richy Z sprayer or GL service department? How is there overall maintance of machine? Yes after 3 PG machines maybe a lesson learned but I have liked them. But there is always an issue that arises with them. My 2 cents.
