I went to Ski Net Sports in studio city because they are recommended here as a bootfitters and they did a good job mounting my ghetto's, and were really nice guys, but they charged alot. It also seemed to me like they had the "new guy" mounting my ski's which pissed me off a little but he did a fine job.
Recently I went to Doc's Ski Haus on Santa Monica Blv. and Berkeley (Just take Santa Monica exit off 405, head towards the beach, and its on the right with a big ass sign). I went there because they quoted me literally half as much as Ski Net for binding repair (charged me $20 so basically just the price of the brake with no labor cost, and Ski Net said $40). I have to say it is really awesome. The tech guy I talked to was like 100 years old and did the fix in about 5 minutes.
They also had the best gear selection I've seen, and are the only shop in LA I've been to that carried Full Tilt's. They also carried the Salomon Suspect gloves which I really wanted to buy but could not find anywhere in LA at the time I was getting gloves. There were a ton of people in there and yet I was in and out in 10 minutes.
So yeah, bottom line they will be the only ski shop getting my buisness from now on. If its closer for you Ski Net is a good shop with knowlegable and nice staff, but I would go to Doc's it will probably be cheaper and they are a bigger place, seem a little more legit.
