Is there a safe website to buy a used iphone 4?

I have an outdated android phone (original htc incredible) and really want to switch to apple products (even if it means no more free music:/ ). I'm working full time this summer so I figured I could shell out a couple hundred for a decent phone, however, I noticed through Verizon's website the iPhone 4's are still 450$ despite the 4S, 5, and soon to be 6, phones preceding it. Is there a safe accredited website to buy a used apple/verizon product? I would hate to get scammed on ebay or amazon with a potentially stolen and resold phone. I'm willing to pay 150-250 for a decent used iphone 4…
if not, is there any decent phones I can buy new for that price?

Try gamestop

There are venders on ebay with 50, 000+ sales and very positive ratings. I've bough phones from a few of them and have done fine. I haven't bought a used iphone off them. They also sell used iphones at Gamestop. I'm not sure how much they sell for, I sold one there for $150.

Yeah
Best avoid to avoid them

The IP4 is months away from being discontinued on release of the IP5S.

Apple only support LAST 3 iPhones, discontinued means no longer sold by Apple, any future upgrades are for supported phones some new apps just WON'T WORK

On 12/09/2012 IP5 announced IP 3GS DROPPED, like the year before IP4S IN, IP3G OUT.
no maths IP5S IN…

It appears that your only research is that I want an iPhone, it may be the cheapest when compared to other iPhones but to invest any money in an OVERPRICED device is a waste as in 2 years you will be using a 5 year old device that came out in 2010. Many have already upgraded from the IP4 in 2012

There are newer phone better phone and they cost a lot less, giving you more than the 8Gb on the IP4, you should look at eg Sam Gal ACE II or the Lumia 620 for phone with a secondary camera microSD expansion Wi-Fi, GPS, DUAL CORE… AND/ &/ PLUS/ + BLUETOOTH MEDIA TRANSFER (Sharing) which no iPhone even the IP5 has.
Here are the specs only if these phones are Gold Plated will it come in above the IP4
