The awareness of where these shops are located and operating will be useful only for professional musicians. I am not one of them, so I think that online musical instrument sellers are a better place to go since not very high quality instruments are required in the start. Anything that works will be useful for a student, so my stance.
Best Musical-Instrument Shop Houston 2012 - Lisle Violin Shop
The inside of Lisle Violin Shop's Bissonnet location is a small space cluttered with instrument cases, a couple of bookshelves with beginning theory books, accessories from cakes of resin to shoulder rests, and a couple of racks of violins and violas. Another room has the cellos and double basses and one violin made to look like a flying V guitar; all are available for sale or rental. But the real action happens in the workshop out back, where five on-staff luthiers make and repair a good many of the stringed instruments for 25 Texas school districts — as far away as College Station, Waco and Tyler — using only hand tools. In fact, the afternoon we visited, Lisle's newest violin-maker had just finished his very first fiddle. In business since 1984, Lisle also offers payment plans, instrument insurance and even delivery services.
