I also agree. I like the suppliers that mention the model number regardless of whatever they've renamed it.
As far as the 901 goes....I'm still confused with that one. I first bought an EM-901 and then found it's not compatible with other 901s, so that was a waste of money and is now a 'disposable' since I can't get parts for it. I also thought all penstyles were the same. Wrong again. The penstyle I have is a kr-108---another waste of money. Then I bought a 901 from Eastmall and now I don't know what a 901b or a 901*insert some other letter* is and whether those parts are interchangable. I also don't know which one is th "New 2009 901".
I've wasted so much money on trial and error. When that counter in my signature starts counting how much money I've "saved" that will be a hugh joke. Money 'saved'? Yeah. Right.....
*sigh*
Hopefully I will have saved money in the long run, but in the meantime I'm still glad to be vaping and I am grateful for ecigs!
