A good alignment is typically around $250 (Note: I said "good"). I haven't used anyone but Tesla because it didn't cost me anything, and they get it mostly right eventually. If I had to pay, I'd use a shop that specializes in performance and track cars. Ideally with manual tools (I believe the hit and miss part of the Tesla alignment is because of the computerized system.)
If you're in San Antonio and looking for somewhere other than Tesla to get your alignment done, Goodyear can get you squared away. I spoke with Tesla and it was $140 for the alignment, but that's without a warranty. Goodyear can do it for $115 with a 6-month warranty or $189 with a 3-year warranty.
