For anyone in the Austin, TX metro area that needs an ASE Certified Master technician I have found a good one.

Brian is mobile and came right to my house, did the inspection and got me a VTR 852 and VTR 64 completed in a friendly and efficient manner.

Excaliber on 183 was recommended on this forum, but as of November 2024 the master credentials were accidently lapsed - they had said they should be re-certified by Jan 2025.
