I was happy with the work they did, can't complain. Being a big shop they probably have more overhead but I don't think the annual inspection was unreasonable. Luckily the airplane just had a Canadian annual literally 2 months before I bought it so there was almost nothing on the squawk list. They did everything they said they were going to do at prices quoted. Mine was an import from Canada so there was extra paperwork and followup and extra decisions to be made which complicated it a bit. I don't think they are a huge Mooney shop, I inquired how many annuals they do per year and the answer was about 20, they did have 2 sitting in the shop when I was there.
Feel free to PM if you want more info and will pass on my cell.
