Domain Central Registries Raising Domain Prices?

I’ve received the following email from my domain registrar dynadot notifying me about a domain price increase

The central registries for COM, NET, ORG, INFO, and BIZ are raising prices this month. Because our margins are so low, we are forced to raise prices as well.

Starting midnight Oct 15 2007 EST, the price of COM, NET, ORG, INFO, and BIZ domains is going from $7.99 to $8.99. To save money, we recommend you renew your domains at the current price before Oct 15.

We work hard to keep prices low. This is our first price increase since we went into business in 2002.

Best Regards,
Dynadot Staff

I’m a bit sceptical about whether the central registries had really raise the prices on October 2007. Why do I think so?
1. No one likes a price rise right?
2. There wasn’t a link to any offical newspage/sources quoting this is true

One way or another, I have no problem with their domain registration service as they usually get a new domain registered within a day, and I’ve several domains registered through them.

Do you know of any other quality domain name registrars where you can register domain names for a cheaper price?
