Honesty is the best policy...I think.

Heres a question for the Forum. I have my PS Audio Perfect Wave Transport for sale here. I purchased as a refurbished unit directly from PS Audio. In use, it will occasionally freeze up and by that I mean the remote or touchscreen will not function. And by occasionally I mean not more than once a month. The first time it happened to me I called PS Audio who told me to turn it off at the back, wait 10 seconds and turn back on to cause it to reboot which solved the problem. They told me it was normal like with any computer. I think it happens more often when I am playing discs I have burned at home of hi-res files. I have also done some research online and see that this is very common with this transport. So, now that I am selling the unit, I have mentioned that this is something that can happen. I don't want someone to purchase the unit, have it do this and then accuse me of not mentioning it. It has, of course, freaked out potential buyers. At the same time there are several other units just like it for sale with no mention of this and I know this to be a quirk of all of these units - not just mine. It works fine and I have enjoyed it for several years. I am selling only because I purchased a DMP that, what a surprise, occasionally does the same thing.  What would you do?
