@Mateya49,
                      I recently purchased a HET 70mm fan from EJF, and recieved it in a timely manner.   Then later on I was looking at some of thier (inexspensive)  ARF kits, that was designed to be a high start launch/belly lander.  I shot them an email inquiring about landing gear for it. About a couple of hours later I had a reply back. So their customer service is pretty good in my opinion. 

As for Nitro planes, and Banana Hobbies. Well there higher end airplanes, Jets, etc fly really nice, but the electronics in them are lacking. From either place Ive had to replace atleast a servo or two on every  airframe Ive purchased from them. Fortunately I have always had one of those servo failures while rigging the flight controls and not in flight.  But as for there customer service................  Well they both are a little lacking in that department. However I have recieved response's back from them but not nearly in as timely a manner as EJF.  But................  They do move alot of product and are quite busy as some of there product is lacking in quality.  So it is my opinion that either they are super busy in there customer service department, and or they are very understaffed.

But to answer your main question. Yes I shop at EJF and Yes I will continue to buy stuff from EJF.
