One of the clubs local to me started out as a group of guys with a fairly closed mentality. They had gotten tired of events interrupting their flying, didn't like the newbies showing up making breeches of etiquette, were annoyed the pilot training time got priority over dues paying members one evening a week, and just flat out didn't like some of the guys they were in their clubs with. So they started a club that would have none of that- no events, no pilot training, membership would be by approval (you had to be somewhat experienced and had to "act right" when you came out to the field for the first time), and everything would be decided by votes. That club started pretty big and financially strong, but soon enough started to dwindle as attrition took its toll. So then they started hosting events on their crappy crabgrass runway to pay the bills. More left. Now they barely keep the facility open, and their volunteer force is practically non-existant. They do well just to mow the runway often enough to fly off of it. I expect they will shut down within 3-4 years.
All of that is to say that hanging on to a club that doesn't have enough life in it to grow is just a waste. If you want to pay triple the price to be away from the bigger club as long as you can, then I suppose that makes sense. It sounds fairly certain you'll be paying 5 times the price soon enough, so it's up to you whether that's a good value. But what you can be certain of is that at those prices you will attract zero new members over the next few years, which means the death of the organization is certain. So invest accordingly.
