Wench questions

I just purchased a used 2013 Yamaha Grizzly and would like to put a wench on it The guy at local Yamaha dealer said I would be paying for the name if I got the Warn Yamaha wench they had there and there were cheaper ones that are just as good. I read that for the Grizzly I should get a 3500 lb wench. Since money is important to me what wench would you guys recommend ? Do I have to get the mount kit at Yamaha or do people who make the wench have the mount kits ? I also have a heavy duty bumper on it , would that have to be removed or would it be in the way when operating the wench ? You guys have been great help with all the dumb question I have had so far , I am new at the atv thing and just want some good advice. Thanks
