Teresa - I think it'll be worth your while having a read of the site reviews. You'll find opinions vary. I own Janty KB's and 901's but if I was to give a short recommendation it'd be:
1. Hold off from making a quick decision - Janty are due to launch new devices any day now. Janty products (especially the KB) are built well and are supported by excellent customer service. You say you're looking for a 'cadillac' - (awful wide boat of a car!) - if that means quality then Janty do that well.
2. The 901 is a good short-term performer - you need a couple of spare atomisers and several batteries. The 901b looks good, some ladies seem to love the pink model and it comes with various colours of LEDs. I like the 901b (black), it attracts more attention than the Janty but - it just isn't in the same league for quality, it doesn't come with a 6-month warranty and it doesn't deliver the same throat hit. 901's are fine - but for the few bucks that are in it - you'll be much better off getting one from a reputable US supplier.
3. The Screwdriver has got excellent reviews and you'll not have the battery problems that come with 901's and Janty KB's. Although it uses a 901 atomiser the reviews report a much better smoke level and throat hit. Like the Janty KB - it's not cheap.
4. Read the
http://www.e-cigarette-forum.com/fo...cussion/3372-e-turbo-my-new-invention-22.html thread - there's a new product in development that sounds very promising and may be on the market soon.
(When you have time to read the threads here you'll soon learn that 'cheap' is a highly debated issue. It essentially relates to the difference between initial outlay costs and maintenance costs which are significantly reduced if a usage warranty is offered - like Janty's).
Hope this of some help. Don't just take my view - I'm sure there are others who'll have worthwhile advice.
