Okay, I've basically narrowed my choices down to these three amps. Specifically, the Marshall and Splawn used vs. the EVH new. From where I stand, the pros and cons are as follows:

Marshall JVM410H or JVM210H

PRO
Great tone
That Marshall "feel"
Nice cleans
Thick overdrive and sustain

CON
"Everyone has one"

EVH 5150 III

PRO
Great tone
Decent cleans
Thick overdrive and sustain

CON
No reverb onboard

Splawn Quick Rod

PRO
Great tone
Decent cleans
Thick overdrive and sustain

CON
People say that the Splawn amps are "unforgiving," that the slightest bit of sloppiness will be highlighted. I haven't had a chance to plug into one so I can't quite wrap my head around this.
