How To Price This Truck

Hello forum! It is time for a new Tacoma. My current 2005 PreRunner SR5 has slightly over 200,000 miles and a blown head gasket. Cosmetically it looks pretty good. I am not using it for a trade and will be selling it as is. What should I sell the truck for (ball park of course) with a blown head gasket? I know several people on here could fix the problem on their own but I don't have the skills, tools, etc. to take on the job and the local shops and dealers around here are wanting anywhere from $2400 to $3500 which is not going to happen. Thoughts, ideas, suggestions? I am just looking for some direction here, not a definite dollar amount. How much do I take off from Blue Book value due to the busted head, etc. Thanks!
