Yes the price will be going up to $250 once the beta version is released on the new site. Existing users always receive updates free of charge so the best time to get your copy is ASAP if you want to save $30.
You will receive a product key from the new site once I port the latest customers over just before the launch, so keep an eye out for your key in the near future if you do purchase PixelCNC from the current website.
Thanks for the offer to help with the web side of things, I'll keep you in mind ;)
