Hey Shady,
Depending on what your looking for you could go with a 901, m201 or 510. If you want a mod then try a vapre51 or silver bullet.
If you want a 901, I would order from Katy @ the smokeless shop. She has great cust service and a really good starter kit. Her eliquid is very good to. She was the first vendor I purchased from and she called me when I placed my order and talked to me for about an hour to make sure I was getting the right device.
If you want a m201, 510 or vapre51, I would order from Shawn at litecigusa.net. He is the greatest. Great service, will help with any questions you have and you can't beat his prices. He has been very patient with me asking questions and generally being a pain in his patooty.
If you want a silver bullet you can get that from Rob at altsmoke.com. He has a good reputation with his cust. I think he is taking pre orders for the next batch of sb's.
I have a 901, m201, m402 and a vapre51. By far the vapre51 with the 201 atty gives the best vapor, with great flavor and the most like an analog. I will be saving up my pennies to get a silver bullet and then I think I will be set for awhile.
You might also want to search on the video reviews of the different pv's and see which one meets your needs. Or you could be like me and decide that one can never have to many pv's.
Good luck.
