I agree, the fees on ebay have got out of hand. Way out of hand actually.
As far as the sales taxes to be collected from business's selling on ebay or other internet sales avenues, that is the state or Florida sticking it to you, not Ebay.. Sounds like the seller is just following the law, but like you say it should be listed somewhere, but on the other hand a fella should know what there state is requiring.
I think Florida is one of a handful of states that don't have a state income tax so there making sure they at least get the sales tax.
As to the refurb price, it don't seem bad, they are still $199 at Menards around here. That said they still come up on sale now and again for $169. I think I seen before the refurbs don't come with a case, so that might matter to some. So personally myself, unless someone needs one right away and can't wait for a sale, the cost is too close to new when the new one is coming with a case and full warranty.
