• Notice to all BUYERS. You are buying at your own risk. If you do not know the seller then please be cautious and look for suspicious activity. If they ask you to mail a check/money order or pay with PayPal using the Friends and Family option, that is a RED FLAG. Your purchase will not be protected. Only pay with credit card or PayPal using the goods and services options. Do not fall for the excuse that they don't want to pay the PayPal fees. They need to account for that in their sales price.
  • To all USERS that think they need to police the site. New users that come to sell items are not always selling stolen merchandise. No vigilante or lynch mob mentality is permitted. You will be given infraction points if you accuse someone of selling stolen merchandise without hard evidence. You must have the stolen item report with a serial number and/or pictures that match the for sale item to make such accusations. Alert the moderators with your evidence and they will take care of any transgressions. If you do not you will be given enough points for a 3 day time out.
  • Please be aware that we have recently gotten a wave of users that, when researched, are found to be from Nigeria. They are trying to sell products and asking to be paid through Zelle or Venmo leaving users with no recourse if they don't ship the product. If you suspect this activity please contact admin and we will research their information to verify their location.

I'm not taking any new work till mid summer.......and then it would be in Nov before I had an open date.

The 660s I do are very strong runners. I've not had a chance to directly compare one of my ported 661s to one though.
Now that's an understatement if I ever heard one! Your being very modest...

My MMMS660xb is a Hoss.

Tree was leaning towards the guys house,( right of the pic), and down the hill, so I left a bit more hinge than normal. No, that stump isn't beautiful, but that 95' RED OAK would of made a mess of his house had it got to it.

That saw pulls a 36" very nice.
