Bob - Toe, Camber, Caster - All done in-house. After wasting money on numerous bad alignments I recently started doing my own. Watching obvious errors done by laser guided garage monkeys in alignment shops gets pricey and out of frustration you buy equipment to do it yourself.
Simple bubble levels have been used forever to accurately set camber and caster and a simple trammel bar can accurately set toe. I purchased a Fasttrax Caster/Camber gauge. This is a $200 unit that contains bubble levels and you can add optional arms to measure toe if you want. I use a trammel bar is made of 1/2" metal conduit for toe.
I have aligned my Unique, 72 Triumph GT6, 86 Trans Am, 68 Mustang, and spot checked Sharon's 325CI prior to trade in. For shop clients I have aligned a 96 Camaro, 78 Fiat 124 Spyder, 2006 Lancer Evo, and 3 street rods. All with great success.
If you've ever watched a "professional" alignment you see that the person doing it will be happy to get your vehicle specs anywhere within an acceptable tolerance range and does not usually spend additional time zeroing in on a precision value. You'll find that your car can be off a few degrees in camber and caster and still feel stable even if not correct. Toe is a more sensitive subject and needs to be approached with more precision. The Fasttrax alignment gauge is claimed to be within an 1/8 degree. I don't know if I'm within an 1/8 but it's really close as bourne out by my results.
