You should definitely buy real human hair, possibly cut in a ponytail and without any processing. I just won a bid on ebay for a 22inch(~55cm) 100g asian ponytail, and only for 62$... needless to say I can't wait until it arrives. I had 2 another european ponytails which I bought in my country, but neither of them was this long... they were also kinda cheap considering the price of european cut ponytails. The disadvantage is, well, it's shedding if you don't fix the ends with something, I will try hot glue this time, maybe it will hold well. :D I have a blonde synthetic too, trust me it kinda sucks, but sometimes does the job. So if you are lucky and patient on finding it, you can get a good, real ponytail (which belonged to a real woman) for a fair price.
