Hello http://bit.ly/spawner I sell my zombie grinder. It's working very well, you get a lot of xp! I want 10K for it but you can bid. I can also make it automatic, but you don't get any xp. Here are some pictures:
Im sorry but NO zombie grinder will go for 20k, It might sell for 5k if you lucky enough for someone to want one. EDIT: Please read the terms of the selling a spawner
WEll, 10k is a good price, but a seeing that you are not a supporter, so I think 8k or something like that is a good price.
Might buy it, but what exactly would you like for it, because 20k is wayyy to much for a zombie grinder
