I have searched high and low on the internet and with electronic parts distributors for a 'better' version of this connector, but found nothing. In my view, these are simply the best there is if you need to get a non-permanent connection made through a tight space. I use mine for various buildings on my train layout. They make a tight connection, and really ease things when models need to be removed for cleaning, photography or repair. Yes, they are expensive, but if you need something this small that does the same thing - this is the only option out there, go for it!
