Looking for a new league to join this year

I have been in the same league for 15 years. I am looking for another league to join in addition to that one. I would prefer a league that has been around awhile, or has the potential to stay around for awhile. I haven’t done a Dynasty League before, but would be interested in one. I also would like to find one different from the current one I have been in. That one is a PPR ESPN Auction/keeper league. I would also prefer to find a league that has a buy in, under $100, if possible. I am a very a very active player!! Please message me here or email me at mnmike37@gmail.com
