Don't worry it will be worth the wait. Spoken as a fellow SD user.
The beci 801 attomizers will work. Not sure about the others.
I'm able to use my penstyle atomizers from PS. One is a tight fit but it works.
The Janty flavors are the best IMO. I just ordered three bottles of rum....magnificent. I also love their capuccino and am vaping it now. Only problem is its price which is way more than others.
