SPC alignment tool

[Phishfud]

I'm ready to do my alignment, and came across this tool:
http://store.summitracing.com/partde...5&autoview=sku

I'm curious if anyone has used it and how well it works. Considering how many cars I have, I thought a $200 investment (with the toe bar) would be great so I could do all my alignments at home. Not to mention there are very few true alignments shops around here, and I don't really trust the chain stores too much, especially with wanting a prformance setup to go with my car. I didn't know if this tool was just to get close, or if it could truly allow me to bypass taking it to a shop. Any input would be great. thanks alot.
