Found a new one at local Lowes Store for about what parts would have cost

I have experience in repairing these saws and from what I have seen the parts plus labor are more than what you can buy a new one for. Their are 2 places on the web to buy parts from if repairing yourself to make it cost effective depending on the part needed.
http://www.masterparts.net/remindex.html (this place has a minimum shipping charge of $10)
http://shoppingcart.msservicecompany.com (this place does not always carry the parts you are needing and do not have an ETA as to when they will have them either. Hope this helps
