Selling Trend Controls (BMS Controllers)

[Coggs]

Does any one have any experience selling overstocked BMS controllers specifically Trend controllers. The trend controllers all have serial numbers on them and i know there are a lot of restrictions on where you can buy them so i was wondering if i were to sell them on could there be any come back from trend? any info offered would be greatly appreciated as I've not been able to find any info on this topic so far.
