Careful with those guys....If you do a seach on the web you will see that a few years ago they went belly up and did not notify people until they submitted a claim that was when they found out they were sol. I am not sure how they reopened under the same name but they are back. I found that info out when I did a google seach and read some stuff on Edmunds. Continental is another company you might want to look into. GE would be best but I am not sure they are still in the biz.
Think of it this way....$2k today....or $8k if you blow a head gasket?
Spend the $2k...ya never know...you shell out the $8K for a new motor and the tranny drops....
