Think you are wise to think about something better than the Blu. The Blu is underpowered and the short battery life gets old quicker than you think initially. For me, I had to get a couple of powerful batteries and some good strong juice (24 mg/ml), and only then did was I able to power through the cravings. The gear available in both 2009 and 2011 wasn't strong enough for me, so I had to wait four years, until 2013 before vaping would work for me. The cigalikes in 2009, and the underpowered batteries in 2011, just weren't enough. Also, your starting kit often becomes your backup and out and about kit down the line, when the mods/APV's start to look attractive. This vaping stuff grows on you, particularly if you get better gear that allows you to really enjoy it. Anyway, what you may want to look at are the ego/stick type battery setups. Here's my

:
Stick Batteries, known as eGo Style Batteries (entry level, backup, out and about, stealth, primary):
Trusted Vendors shown, but NOT selected based on pricing, you'll still need to shop around. You will need device specific battery chargers (which often come in kits) for these devices. Also, kits often provide two batteries allowing for simultaneous vaping while charging of the backup. Each of the eGo style batteries below have both 510 and eGo thread connections. As such, they are compatible with most toppers, including most Kanger products. Additionally, each of these devices has at least variable voltage, which allows you to adjust and regulate the battery output voltage, providing customizable vapor production, temperature, throat hit, and finding the "sweet spot" for your juices to suit your individual vaping preferences:
1. Innokin iTaste 3.0 vv/vw, usb passthrough, ohms reader, etc. -

2. SLB KGO VV -

3. Vision Spinner -
Vision Spinner VV eGo Battery 1300mAh (3.3 - 4.8 volts, 1300mAh)
4. Joyetech Twist -
eGo Twist 1000 Mah Battery in Black (3.2 - 4.8 volts, 650 - 1000mAh)
5. Smoktech Winder -
Smok eGo Winder 900mAh Variable Volt Battery (3.2 - 4.8 volts, 900 - 1100mAh)
Best Starter Combo kit out there, imho, provides two batteries, i.e., the twist and/or spinner, and two toppers, i.e., the eVod and/or MT3s, among others:

Recommend one eVod and one MT3s topper with one Spinner and one Twist to start. This way you get four different products with the kit and allowing you to experience four different setups, as you figure out your preferences and what works best for you. BTW, you can spend less and get a fixed voltage battery, but you'll have much less vape flexibility and it won't be long before you'll want to upgrade to variable voltage, more than likely, and the difference initially is only a few dollars per battery anyway.
Good luck, keep posting, happy shopping and Vape On!
