if you could have any tool for a christmas present...

Your marring the wrong sister. Christmas gifts are to be a showing of affection, not a life long statement. I would be tickled with a set of Vise Grips, Large and Small. This year my sister wanted to know what I would like for Christmas. I told her a new billfold. I had washed mine and it split. They also bought me a 155 piece tool set at Lowe's that only cost about 60 bucks but that was their statement to me.
I was overwhelmed. They also gave me one of the small magnet screw holders for when you work on you car. I feel so lucky to have someone that cares that much.

My gift to them was a new halogen free standing light system. They just started having to work on their 62Stude Hawk engine and their old ones had quit. I bougth them and then drove the 65 miles to their house so they could have them to use. They were were about to have to go shopping but they live in the country. I live in a small city and have many more shopping outlets. I filled a need they had and I felt good about it. To me, that is what christmas careing is about.
