Hopefully you have a stock of modules put away, as all X10 sells are soft-start and the other dealers in X10 have to buy from X10. X10 didn't bother to give the soft-start modules different part numbers, so you can't tell them apart until you have to replace one of your old ones. I got 2 modules from Automated Outlets last year and had to put a SS in indelible ink on them so I can know them apart in my spare box. X10 needs to be beaten with sticks for that one.
