I love the UAD-1.
It's worth it for the compressors and Pultec alone.
I have the Voxengo GlissEQ and PSP MasterQ, which I love. With the Pultec Pro, I'm stoked for EQ.
As for verb, I suggest you try out the PSP Easyverb. The name sounds cheesy, but its' sound is great. Or check out Pristine Space at Voxengo.com.
