Some folks are recommending the Joytech Atopack Penguin for something small, portable, and easy going. You could also get something like the Joytech Mega e-Go starter kits with I guess you can get up to a 1000 mAh battery.... That's within your price range, you probably don't want to start out with any coils below 1.0, especially if you plan on MTL vaping, at higher nicotine. If you want an aspire starter kit (I'm a big fan of aspire, generally) you could go with this kit:
Aspire™ Premium Starter Kit (Nautilus Mini / CF VV+ Battery) - Vapor Authority. You can then upgrade your tank later if you find the nautilus mini isn't doing the trick. I wouldn't buy a pod system as they are finicky, hard to use, very expensive, and just not the best choice. I'd do some reading of pinned threads around the forums too, to see what features would be helpful for you down the line.
Good luck.
