any one pick up one of those $100 Sigelei mods all over eBay? I just got one today and I have to say it's pretty good. clean, metal case which is nice. magnetic cover. heard the ohm reader can be wonky but mine seems right on so far. decent battery life. I think it's the SX-330 chip? I think it was worth $99 with free shipping. it certainly puts out the power.
