Our 2 offline listers are Auctiva Poster and Mister Poster. You can find info and links to those here: http://classic.auctiva.com/products/default.aspx
The reason people use those over Turbo is primarily because you get free scheduling, templates, and image hosting with supersize images.
eBud is a program that helps you manage your listings. It's a very cool program, but doesn't do listing.
A token is what lets Auctiva do things for you on eBay, without knowing your eBay password. Instead of eBay giving us your password, they give us your token. That way we don't know your eBay password, but we can still post your listings and stuff like that.
You can use any of the templates from all 3 listers with any of our listers. However you would have to do some work to get it to work the first time. It would involve getting the HTML for the template you like and putting that into the other lister. That's because not all our new templates on the Auctiva.com lister page have been converted for the older desktop software.
As to which is faster or easier that's really up to each individual person. There are people that swear by all 3 listers. It really depends on your style of listing and if you are listing uniques or the same inventory, etc. The most popular of our listers is the one on auctiva.com that works in your web browser. If something is slowing it down for you maybe you can post about that and either a user or someone from Auctiva can give you some ideas on ways to speed that up.
