Looking to borrow/test Hammerhead pump

Anyone have a good condition hammerhead hybrid gold pump they're not using? Just wanting to see if it has enough head pressure to reach my upstairs tank and can put out the flow I need. Trying to weigh my option of buying another pump or downgrading impellors in my current pump. Its the same size as what I have so I'll be able to just unscrew my unions and swap it out quickly. Tryin to save 300 bucks. Let me know, I appreciate it!!
