I'm using a Vision Spinner now, and I ordered a Vamo V5. From everything I read, it's one of the best beginner mods to learn on. I'm sure it won't last me a year, but in a month of 2 of having it, I'll have a better understanding of mods.
The V5 I ordered was 32$ from FastTech (no batteries or charger, but you can get good ones from Amazon like I did). FastTech is HORRIBLE for shipping, but they have amazing prices. So if you don't mind waiting a few weeks, I would jump on that. It has all the features any other mod has, but at a fraction of the price. It'll help you learn to use an APV, without breaking the bank.
