MikeyMike,
the "no pros" comment is way off base, especially with me...no foosball board is more welcoming than this one, the fact that you got straight answers to a question of melting solder into men's heads says a ton
are you feeling like you got "big boyed"...you threw out the "coin op, yada, yada" and I gave you some back  

 but my answer was straight up, specific to your situation, stated goals, and tightness with money 

 don't go getting all injured on me
you got a super bargin to get the Whirlwind at $60 and you want it recreationally anyway, no benefit to you that I can see to try and make them counter-balanced men
the only time that makes much difference is in singles or goalie wars...Goalie wars you can use rubber bands or buy rod locks...singles, you will get used to balancing the men straight upside down
when I started playing serious first time around on TS in the 70's, nobody had heard of counter-balanced and the best foosball played in the world didn't have it...you learn to play around it in singles
you can have plenty of fun...save your money and buy some new balls and a light for overhead, these will make a much bigger practical difference in how much fun you have...oh, and buy a few wraps for the handles and a little silocone
