The Dynamo is old. That means you won’t be able to use skill developed on it to play in your local tournaments. There are some in your area - and playing in them will be the best way to learn good techniques. The other is the brand used in tournaments but I don’t recognize the model. Find out. If a Storm or Storm II not so good. It’s the home model. They do make a better home model but I don’t remember the name. Look at tornadofoosball.com for the current ones. They’re a bit pricey, talk to Charles McIntosh at that same sight. He can help identify the model you are looking at and help with any necessary part or maintenance. Check that the surface is completely flat - no waves, etc. Rods should be straight and not pitted. That can be replaced. Balls should be pink. PM me is you want.
