Front End Alignment Los Angeles Area?

I called the following:
1) Simpson Frame- the guy wants $450 for the front-end alignment. $175 per hour. 2 1/2 hours for a front alignment seems really excessive. Can't imagine it takes 2 1/2 hours for an alignment. Being that the last guy (Unfortunately, he went out of business) who aligned it took him under 30 minutes.
2) Marlo-wants $200 for the alignment
3) Johnson- wants $100 for the alignment
4) Tyerman - $150
5) Cars Automotive & Muffler $150-200

Thanks for the information.
