Don't waste your time with a fast Ab... Neo is now freezing based on buy speeds. I am getting frozen daily, and Most of the time I do not even last long enough to get restock banned. My times are .2-.6 seconds...
I have 1 word for you! FAST that is all that counts. Under .5 second buy times and your golden.
On a decent connection that is.... I have an 8.8MB/s if you need a speed tester I can do it. I use another ab won't say which and I get consistant .5-.7s buys..
