I am almost ready to purchase a shaver 165, it has 170 gallons of water compared to a wood master 4400 which has 112, which is better? more I would think. Shaver has simpler controls, $450 extra for ash grate on the woodmaster. shaver I am spending about $5500, that is with heat exchanger, 40' of tube to get to the house. According to the website their steel is the thickest of everyone. Complet package without ash grate is $7300 for the woodmaster. Am I making a good choice? what do you people think?
