ive had several but my favorite i bought from ebay it has a built in ladder that makes it simple to fill cant remember the name but cabelas sales one just like it in 200 and 400 pound capacities
i have the 200 its plenty big. i put a solar panel on mine and has been running constantly for @ 2 years. i see a 400 on ebay but not a 200 but you may could write them and see if they carry the 200 also. the varmint guard is a good investment also. those darn coons are very hazardous to the motors. dont know how they can get to them but they surely will. gets very aggravating
having to carry in a ladder so the built in one is GREATTTT
