I would not trust any of the registrars, not even Hover.
> That makes me think they have control over the price
Well yeah, registrar is a business, of course you have some say on the price you sell your domains... But there's a base price that is set by the registry behind the registrars
As an example, the .com is sold by Verisign (the registry) around 9 USD for the create/renew, but around 50 USD for the restore, depending on the negotiated price between the registrar and Verisign. So basically no registrar will allow you to restore a domain in redemption period for less than 50 USD.
All others I've tried have had unintuitive interfaces that make me want to scrape my eyeballs out.
GoDaddy the worst among them.
