In strict terms of price, the Alpha Crossfit package on rogue fitness is $1,550 for :
320lb bouncy plates (365lb total load w/bar)
1 base level oly bar w/decent entry-level clips
2 sets of kettelbells (35 and 53 lb)
gymnast rings
dynamax ball (I have no idea what this thing is)
battle/climing rope
speed rope
Adding in a squat stand ($350), a bench ($150), and a pull up bar ($100?), tax and shipping,... let's call it $2500. Actually let's round up to $3,000 for a system that I would call "holy shit you have a nice home set up" to include some tires, timers, floor mats, chalk, dry erase board, video camera, etc. So you have a payoff of 20 months with a useful life of at least 20 years. The cost difference is about $30,000.
Not even touching on feelings of crossfit, that is a lot of cash to consider for something you can do yourself. I could build a garage, add in key-card access for friends, and equip it with a better gym than a standard crossfit box for less than that price.
