Welcome to the world of domaining. Unfortunately, I don't think any of these are worth reg fee except BigPizzaHouse.com, but then you have to hope a pizza business with that name shows up and then you are probably looking at a sub-$100 sale.
Wow these guys are rude and not sosupportive. I would have to go with BigPizzaHouse.com as your possible as well but as it stands it not so valuable. Why not spend the $1-5 a month for webite service from godaddy and turn it into a Recipe site for Homemade pizza products. Throw some pizza related adds on there and see where it takes you once the name gets some play. That is if you can afford the time/money. not so much time though cause for $1 dollar you wont have many pages to keep up with and you can keep the same recipes on there forever. Even sell flour and what not in the future if you chose to do so.
Guy is wrong about Sky progress not meaning anything cause it could be something dedicated to cleaning up the ozone/pollution so to an organization that comes around might want it. same scenario though start a one/two age blog about clean air and eco-friendly stuff and you might stir some attention
A video is Not an Example. It is a Video! so you can have a written examples or video examples so it has potential as a site giving video tutorials. If you are good at doing something take videos and upload them so you don't have it sitting there and hope that others load theirs as well. make a youtube channel and facebook page for it.
RoboElectric is an awesome name and you can try and market it in electronic music section as a possible name for a band. There has been wind up robots in the past by the way so don't listen to the "Robots cant work without electricity" useless comment
I'm sorry if I wasted your time because I really don't have an appraisal price for you but wanted to show what the potential of your site could be in case you or someone overlooked it. Good luck to you
