I would like to hear +'s and -'s for any of you that have used both? I just put in a pump stand that was sitting for a few years it has 2120's. I have all my old 310's that I was going to sell, but now I'm thinking of keeping them. For what I will get for them I dont know I should sell as I have never had any issues and I dont know much about the 2120's. Thanks for your opinions in advance.
