HUO Stern Pros are a great value.
They are as fun as hell to play. Rules are good on them. You get a chance to sit back and see how code goes. They are available on the market. Most do well on location. Stern makes four of them a year?! They hold their value well. Since they are so new they are easy to buy because condition is usually not a factor and Stern has good warranties on their games.
Now older games are fun also. The prices have gone up and a large group have gotten close to the Price of Stern Pros and some higher. Prices have gone up, but they really do hold their value very well and always have good demand.
Either way you go newer or older you will have a lot of fun with these games and good resale down the road.
