I had this as a kid and had a blast with it. Due to it's rarity and finding one in good shape it's pretty hard to come by. Plus it usually sells within the 150 to 200 dollar range in good condition. So I missed this recent auction and contacted the seller and gave him an offer because the time was right and I had to get it! After a 30 year break, it came in the mail today and I had to try it out. Good to know it works just as good as the day it was made back in 1978. So let's give a cheer for Remco and the Hulk's instant muscles!!!
