The reason people tend to push eGos to start out with is because they're 510-threaded, which means that their larger, better-battery-life batteries (over the cheapie convenience store models, anyhow) can be used with cartomizers, atomizers/cartridges, or tanks. This allows you the option to experiment a bit with different things and to find out what tastes good/works well for you.
For me, personally, I like tanks. I have an eGo battery with a Riva-T tankomizer on it at the moment. Would I like to play with one of the higher-priced mods? You betcha. However, my start-up cost me about $50 for the eGo-T starter kit, about $70 in extra batteries/tankomizers/cartomizers/different tank variants/atomizers/drip tips, and about $80 in juice from a few different vendors to sample. That comes out to about $200 total to start out with, rather than just $200 for the starter unit itself and nothing to use with it.
This is not to knock the Provari that was mentioned. They are great units. So are Darwins. So are a lot of the mods out there. They're fantastic. They give you options, too.
... but as someone who's just getting familiarized with all of this stuff, I'll be honest, the ability to test out stuff for relatively cheap, while experimenting with nicotine levels/flavors, and still maintaining a budget is a far better option.
There's a couple box mods out there that are also really inexpensive, about the same price (or less) as an eGo starter kit, and they also would work well for you in terms of having experimentation capabilities (just make sure you take note of whether it's 510-adaptable or another system). They do not allow the same kind of tanks, though, so you'd have to look into what's available in that regard.
No matter what you do, welcome to vaping. It's fantastic. It's wonderful. And it's kept me from wanting to smoke for almost a week now.
