I'm trying to decide what little triming saw I'm going to keep. It's down to the ported MS180 I already have, the Dolmar PS-401, or the Redmax G3800AVS. My Dad has a stock MS180 to compare to my ported one. I've got a 401 here stock other than a muffler mod. I'm also considering buying a G3800AVS for comparison as well. Ideally, I would run all three stock saws in the same 10" Poplar log I have here. I'd then port the Dolmar and Redmax and compare them with my 180. I'm not sure if my ambition will last that long though. My search is driven with the hopes of finding a replacement for the 180 that has a vertically split magnesium case and bolt on cylinder. RPMs are important on a trimming/limbing saw. My MS180 turns 14,400. The 401 was 12,000 stock but is already at 13,200 with just a muffler mod. The 3800 is 13,000 stock. A couple questions. Which saw is best build, most durable? Will either saw equal or out perform my ported 180 once ported? Which one would you buy? I'm not interested in any other suggestions for saws that are over 9.5 lbs or don't have a pro style construction. I have a MS260 for that. Here are links to the above three saws. MS180, PS-401, G3800AVS
