Thanks for the input. My buddy does a heap of car work and A/C work as a side business. In fact when he was first starting work as a teacher 25 years ago in Ft. Worth, he made more money in the 3 months in the summer doing mechanical and body work than he did in the 9 months as a teacher. His 20 year old guages are just worn out I think from use. He is currently disabled and supporting himself off odd-jobs. I owe him a least this favor and want to find something he can use for a while.
I'll take a look at the suggestions and probably head toward the higher end. Oh yeah, and remember the beer too!
I also really appreciate the thought and consideration given by the members of this forum to assist each other. I'll let you know the progress in a couple of weeks.
