I was in need of a couple of CX22 replacement fire buttons, so I contacted Best Electronics and found that they are "down to the very last of them". As such, there is a limit of 2 per customer. If you own a CX22, you better act now, as the shaft on these buttons tends to break over time, from normal play.
BTW, my transaction started with an brief email request and concluded with a 5 minute phone call. Everything was handled over the last 12 hours (Brad actually responded to my email yesterday, Sunday, which I was not expecting ) and the entire transaction went very smoothly, which has always been my experience.
Say what you want about their website, but IMO, Best is still the best!
