Nice of you to offer, anyway. I have 19 8x10 holders and that's plenty for me. For what it's worth, I prefer wooden holders as most brands are lighter than more modern plastic holders. There are some exceptions, of course, as in everything! I hope the seller's idea of a "reasonable" price is in fact reasonable and someone takes advantage of this.
Around here, it seems people use Craigslist because they think they can get more than by selling on Ebay. I don't think that works very well: the supply of idiots with more money than they know what to do with is limited!
I use craigslist only because I like touchy feeling. I've found great deals this way and I don't have to be wondering about the ebay sellers idea of "Mint" because ebay has been one big poo poo Pot lately.
