I bought the blue Holzfforma 272 on sale 2 years ago for 89.00 plus shipping which worked out to 152.00 to my door. I wanted to modify this saw and did not want to lose a lot of money if it did not work out. I did minor port work, installed a highway pop up piston, gasket delete, and a modified muffler. The saw responded very well and will pull a 24 inch bar with full chisel chain buried in Oak. So far it has help up very well. Now Holzfforma has the blue 372xp on sale for the same price so I bought one to modify. I will use a big bore with pop up piston and I am going to carefully do more aggressive port work to this one. I wiill also mod the muffler.
