Their Olympics group buy from last year was awesome.
The Fender pack is good, but I like the Princeton from the custom shop better than any of the amps from that package.
I also really like the Orange AD-30, and the Silvertone that comes in the Hendrix pack. If you are looking for the 80s sounds the Slash amps are pretty good. I have demoed the Dr Z and ENGL amps and may get them. Less impressed with the Soldano/Jet City models than I thought I would be.
As for effects, one of my favorite is the MXR chorus from the Slash pack. It's more airy than watery and adds a lovely shimmer. I am also curious about the Wampler stuff. There is a free Cranked AC Wampler plugin made by Le Pou that just rocks. It makes me want to check out the Wampler models in the AT custom shop.
