Hello and Welcome Jblindy,
My answer to this is that if you genuinely like the set and want it for your collection, you should acquire one. But if money is a concern that goes beyond just wanting the set because you like it, then it might be better to wait. Modern U.S. Mint stuff often goes down in varying degrees after they hype on the product goes down. So, it's really up to you based on what your reasons for collecting are and your collecting goals. I'm probably a bad one to ask about numismatic investing. I now only collect one thing, which are coins of Roman Empress Faustina the Younger. Even after almost 1,900 years, the vast majority of her coins are still extremely common. Her coins are almost like the 1980's baseball cards of Second Century CE coinage. I'm certainly not going to be able to retire on a Faustina colllection. But I'm fascinated by her and I love her coins, so I buy them for that reason....for love.
