Value is up to the individual.
Some of us here are cheap and wouldn't pay more than $20 for a deluxe no matter how rare it is, while others are more completist and/or desperate and go a lot higher for the rarer figures.
The seller isn't charging a "scalper" price (as some have pointed out that the entire lot, if complete, isn't over-priced), so if you are happy to pay that price, then you will enjoy it just as much as if you waited months or longer to find something cheaper. (probably even more-so, as you'll have the toys sooner, while you are in your "honeymoon" phase of renewed interest in TFs toys)
Just check the listing carefully, like any other ebay purchase - see if they are reliable with good amount of feedback, and have been around for a while on ebay, make sure they ship to you (worldwide), and accept paypal.
