@Chad- That link was a promotional video for a gym! A lot of Crossfit affiliates are completely out to lunch. They want middle aged men and teenagers to "come bleed with them".
Crossfit can be good but often isn't. If your box has well-informed, reasonable coaches who actually program to their clients instead of just throwing out random workouts you're in a good gym and should stay there if the money and motivation keeps you going and improving. The novice effect of rapid improvement in a new physical pursuit (or not training consistently over a lifetime, or not trying half of the Crossfit exercises before arriving) leads to a lot of trainees feeling like they have made more impressive gains than they truly have, and the variation just keeps you thinking you're improving while you are simply maintaining average or below average outcomes on any one of the single training outcomes of Crossfit (gymnastics, olympic lifting, powerlifting, bodyweight exercises, running, skipping, wall ball?, kipping chin ups?) while a reasonable, consistent approach to one area would have you eclipsing your former results at a Crossfit gym.
Training with friends is awesome- Crossfit friends (like facebook friends) are not your friends, rather it's a pretty lucrative business model for a successful "box" owner and for Crossfit itself(I've heard estimates of $25-30,000 to set up your average Crossfit gym, and then charge $1-$300/person/month to train depending on your area, and $1000 for a certification to open a gym- you can't fail the certification).
Having paid that much for something for an extended period of time, anyone would be defensive, but if you examine the expense coldly like any other expense it is an inefficient use of resources, both time and money. It's the same as any inflated expense that the majority of people "can't" live without. Imagine your reaction if someone said they needed to spend $3000/year to have someone help them cook and eat well. Sure it's an investment, but one that would be better spent on good food or learning to cook for yourself.
If you want to train with others, try calling up a friend and meeting up for a run or sparring, or soccer, or working out outside. Those things are great, and give all the same motivation as a Crossfit gym without the cost.
@northman- I think that a pull up bar and any one of a barbell/dumbbells/kettlebells, even bands, would be a great start and then you can slowly add quality items to your collection as you feel like it and take advantage of your location. All the best.
