I've probably ordered from eHobby about about 7 or 8 times as well. Sometimes I get a tracking number, sometimes I don't. Usually my order arrived within 2 weeks, but there's usually a 3-4 day delay from the time I order till it gets processed and shipped. But never had any issue with them to date.
I just reviewed my order with them and am a bit disappointed in myself though. I thought I had ordered 2 spare TM mags for my WE Hi-Capa, and I realized what I ordered was actually WE mags. Dammit. Must read product descriptions more closely before I buy. I could have gotten TM mags for about $5 each than the WE mags.... Oh well. Next time...
