1st Nexus 7 still a good buy at $100? {resolved}

I just got the HTC One and happily enjoy my iPad (4th gen), but I kind of want a smaller tablet as well. I was just cruising around Craigslist and found an original Nexus 7 for $100 with some shitty case, but I was wondering if it was worth that much with all of the performance slowdowns I've heard about since it came out.

Update: Decided to pull the trigger and buy it. Thanks for the comments. :)
