That's a great deal! I spoke with a few people regarding what's right for my tank and After getting a clearer picture i have concluded that I'm more in need of an mp10.
I would jump all over this however decided to look for the mp10. Does anyone have the mp10 for sale?
You are probably going to need to buy new. These don't get sold very often. Try evilempire.com(reefcentral) and other big sites or ebay. Google" vortech mp10 craigslist" and that will give you results from all over.
