WTB VSonic GR02 Bass Edition from HIFINAGE

Hi guys,I'm planning to buy VSonic GR02 Bass Edition from Hifinage.com as it's the only place to get this superb IEM. Is this store reliable? Any alternative to Hifinage or Vsonic GR02? How's SM E10M & what's the difference b/w E10m & E10?

Please reply guys,I'm in dire need of a good IEM within ~2k
