EGT probe problems

I just bought some new Defi BF gauges in December 2006 and they look great and worked great. Does anyone have these gauges? My EGT Gauge, my probe has died and needs to be replaced. Anyone else have this problem? What should i replace it with? Back to defi for another defi probe or a different make one? What should i do? any ideas. I cant go back to my old shop where i bought it because i had a falling out with them and I no longer talk to them. They were the ones that bought the gauges. So I would rather just buy a new one from DEFI or another manufacturer. Any ideas?

Thanks
Ben
