I think the "Swisschamp without the pliers" is actually called the "Champion." There aren't too many people looking to trade a higher end folder for a bunch of cheaper ones, but you could sell the ones you have and buy a nicer knife. If you're planning to sell a decent amount of knives, I'd suggest you invest in a gold membership to sell them here, they become well worth it very quickly. You don't have to pay the extra 7% or so for each sale that ebay charges, and you'd generally be selling to a more knowledgeable group of people.
As for a nice knife around $100 or less, you take a look at the Kershaw Speedform 2, Benchmade Griptilian or 710, and Spyderco Manix 2 or Paramilitary 2. A lot of it really depends on what you want in a knife, one of the most important distinctions being whether you want a thinner knife that carries more easily and slices better, or a beefier knife that won't cut as well and is heavier, but is more durable.
