Your willingness to spend as much as $160 gives you a lot of good options and even leaves room for you to experiment with different delivery devices to find out which you like best.
Delivery devices are the vessels that hold and vaporize the ejuice. The easiest type to use are called clearomizers (clearos). In my opinion based on just 3 months of being a member of the vaping world, clearos were gaining in popularity even before the introduction of the first glass model, the Kanger Protank. The potential confusion between clearomizers, cartomizers and atomizers is increased by the fact that many sellers don't seem to know which are which in their website advertising.
It's a big confusing world of equipment out there, so instead of writing a thesis, I'll cut to the chase and give you my recommendations, which are guaranteed to be disagreed with by other people with equally good intentions of helping you find your "set-up".
The following items are all from US sellers from whom I've purchased and I vouch for the customer service. You can generally save money if you buy from sellers in China but I choose the quicker delivery and easier resolution of any problems that I get by buying in the US (even though the majority of vaping equipment is manufactured in China.)

Vision Spinner VV eGo Battery 1300mAh (Get 2)
Kanger EVOD eGO Bottom Coil Clearomizer (Get 2)
Atomizer Head for Kanger EVOD eGo Bottom Coil Clearomizer (Get 10)
This amount of purchases from My Vapor Store will be $77 and will therefore qualify for free shipping
From Mt Baker Vapor, get
SmokTech Ego Charging Bundle - Mt Baker Vapor - Electronic Cigarettes This is a better charger at a cheaper price than the once sold by My Vapor Store, and comes with a car charger in addition.
Plus, get at least 100ml of ejuice from the same place (Mt Baker Vapor) which can cost as little as $22 (more if you buy a variety of flavors in smaller bottles but still great prices for quality juice).
The amount of purchases from Mt Baker will be $35 (or more if you choose) and shipping will be about $3.
Total cost: $112, and you will not only have quality equipment that's very economical for continued use, but you'll have EVERYTHING you need, with replacement parts and back-ups for 30 days or more of vaping unless you use an exceptionally large amount of ejuice.
Oh, almost forgot. Enter ecf10 in the coupon code section when checking out at Mt Baker Vapor, for 10% off. If that doesn't work, try "mtbaker". There is always a 10% off code or two, so if neither of those work I'll find you one that will.
There is also a 10% discount code for My Vapor Store. For the month of April, it's H8EMZ. I suggest ordering an additional Evod clearo when this knocks your total purchase down below the $75 minimum that's required for free shipping.
