Hardware cab sims?

Disclaimer - I am a sucky guitar player and am not versed in the finer points of cabinet emulation. But, I am very fond of the offerings from these guys. I think the company's name is audified, and their cabinet and pedal sim product line is called audiffex. Their free stuff is very feature rich for a freebie. So, you can get a good test drive in without spending mad bank. If you get their newsletter, they will run these insane deals where you can pick up stuff at like 70% off.
