Im new to the forum. Maybe you guys can help me out. Im trying to figure out if its worth selling my first gen echo cs600p to upgrade to the new cs620p, or send mine out and have it ported and modded? My saw is in great condition but would like more power and faster cutting speeds. The saw is only used on my property. After searching this forum I see mastermind and snelling seem to be very liked, And do great work. How to you get ahold of these guys? I tried to Pm them but I'm not sure I did it right or they are just overwhelmed with Pm's. Is there A phone number or email address for them. Any help would be appreciated. thanks
