$50 to me is a great price. but then i have my own gym with most of what i need and workout at a small private gym at a guys house. we just all pitch in for anything new we want otherwise there is no price. and at times we will bring some of our own stuff from home.
i would say that i would pay to go to that private gym at least once a week. the knowledge and motivation that comes from it is priceless. so i would say pay the 50. you may just have to give up something else in your budget. like eat out less, carpool as often as you can to places, etc.
i gave up drinking, eating out except for once a week, and most of my expensive hobbies (that were really a waste now that i look back) and was able to get my house and start putting together a home gym. i am happy i did nearly 4 years later, much happier. and that private gym did not come along till last year. i kept searching for a place to train and after a while got lucky. they exist, you just have to keep searching.
there is a local powerlifting based gym and i dont like the place at all. there is no team atmosphere but there are lots of cliques. that little private gym we are all friends. we hang out outside of the gym as well. we even go to meets to support each other even if we do not compete. and yes, we even have team shirts.
so i would say try out the 50/month gym. make sure you feel good in it. get the help and motivation you need. otherwise go to the cheaper gym and start looking for guys working out in a garage to train with.
