The shipping is always the part that kills you brother. Northern looks like they got some good priced tanks with fairly reasonable shipping. But I think they'll all have bottom drains.
I bought my 125 gallon at the local tractor supply. Listed at $199. I told the manager that I was thinking about buying one on the internet for $175... He called up the site (National Tank Outlet) on his computure, verified the priced and said he would match the price.. So, I got it at I-net price... no shipping cost.
I called my local Tractor Supply. They seemed to be a franchised outlet and you might have one near. Go to their website and check your state to see the locations. They have a 100 leg tank for $250.00 which is reasonable. http://www.tractorsupply.com/
