I think the words 'mods' and 'upgraded' may be a red flag for some. Unless you know a little about the product and 'upgrades' it may be perceived that the original product was flawed if it needed modification. Factory upgrades and mods performed by known reputable companies wouldnt scare me off if I did my homework.
Also, the question arises, if the seller went to the trouble to have a unit upgraded and then sells it, did the upgrade fail to improve the product to a standard hoped for? This is especially true when the ad says something like "fresh back from manufacturer for upgrade". It does seem to me that if you invest in upgrades you shouldnt expect to get much of that money back.
