I have a question to ask... ; Through out the years I call the plumer to clean up the root in my drain line(4"), all the money I spent I think it is a good idea to buy a drain snake machine. I saw the RIDGID/Kollmann K-380 W/C-45IW at Home Depot can run the 1/2" Cable up to 75'. Do you think it is good idea to purchase with my limited buget? I really need your advice, Thank you very very much!!
