ozstockman, you probably mean it tongue-in-cheek, but it's unlikely to be a good idea to put a note like that onto your listings.

Buyers tend to look at evidence of a seller being affronted or put out by eBay's policies as ... something of which they don't want to be aware.  It 's a bit like a mediaeval comedy where one disgruntled peasant is egging on the rest of the disgruntled peasants. "Them up at the castle are taking a good fifth of our grain while our women and children starve; where's the fairness in that? I tell you, friends, we've got to fight them with pitchfork and shovel. Them with their silks and samite and spices from foreign places - what right have they got, then? Come on, let's show them what for!" Other peasants shout: "Yes!" "That's right!" "We'll not be downtrodden any more!" "Down with Lord Fatguts!" "Stand up for our rights!" "They're our carrots!" "Can't even buy a loaf of bread!" "My little 'uns are starving!" "Grrr!" ... and then along come the lord's retinus and guards: "What's going on here? Are you inciting unrest? Anyone dissatisfied?" ... A huge silence falls, and if the first peasant is unfortunate enough to rely upon his fellows, he will find himself the lone little voice.

Basically speaking, your buyers won't care about your (their seller's) issues; primariliy they just want a hassle-free transaction.

By all means you can switch to "no returns". I think for many sellers it's the only way to mitigate high risks with what they sell.
