The Corsair Kit is getting pretty hard to come by... it is cool...
The rest of the kits look great..
Bob, you can do a ten day auction .. and if you list them on Thursday.. you get 2 weekends for people to view your items.. Many of the top regular model airplane sellers list their items Sunday evening... for 7 day auctions..
I wouldn't hesitate to put a $50 reserve on any of these kits.. they are all going to sell at a $9.99 starting bid..
Lately many items don't get close to the end price until the last hour.. rest assured there is a great crowd of bidders on model airplane stuff out there... some collectibles/categories have really taken a dive during this recession.. art has been the big looser.. ceramics ( my mom collects dolls and Toby mugs) ... My gal says .."He knows more about dolls than any guy I have ever known."

... my mom and I have "invested" once to twice a week looking at dolls for the past 4 years.. she is 80... and it has been one of the highlights of my daily life to spend this time with her.. collections are a great way to take an interest in another persons life.. my own quote..."Collecting isn't about things, it's about people." At lest that is what I have have experienced..
I suspect you will get between $300 -400 for these 4 kits... maybe a little more..
Shipping.. it costs about $15.00 to send a large kit by parcel post.. That is what Sig charges for a Chipmonk Kit. The Flite Steak may ship for about $12.
