GH3: why only Samy's?

Got my GH3 3 weeks ago from BJ's in Canada - great to deal with, discount applied and fast shipping. At that time Samy's did not have the GH3 in stock, but since I live only 70 miles from the Pasadena Samy's store, I was able to test both the Lumix Vario X Power Zoom 14-43mm and 45-175mm lenses mounted on a different G model at the store. Later, ended up buying both. They gave me free shipping and they still have the 45-175mm listed at $299.00. Samy's has several outlets in So. Cal and I have shopped, tested and purchased from them for a long time. They will work with you for the best price and answer your questions. They are solid!
