I have never ordered from Banana Hobby so cannot comment on their level of service or lack thereof, however...
They do advertise (and presumably stock) some rather interesting models; Large-scale warbirds, EDF jets etc. One place I have found that carry alot of the same items is Ready2Fly
I have ordered a number of times from these guys, airplanes, spares, tools, accessories and such and have never had a problem with their deliveries or delivery times.
Anyone who has been put off by other posts relating to Banana Hobby might want to try these other guys out instead.
