Hey "ofmoss" - how about under your profile giving us at least your first name and the area where you live? Fun handle you came up with, but spelling it out and even trying to remember it is going to get old real fast.
I think a few members here have an Alligator so they would know better than I.
I have played a few in stores and they seem okay to me.
But here is the important question - do you know which pickup is in it? If it is the factory installed biscuit bridge version of the Fishman Nashville, and the guitar is in good condition then under $500 would be a fairly good price. But not a screamin' great deal. I think this one when new with the Nashville pickup goes for $649.
My first resonator was a Gretsch Alligator, and I still, quite often, pick it up and play away on it. These are great little entry level resonators. I have heard stories though of the quality control varying a lot between instruments, with some people having great guitars (as was my experience) and others having a lot of issues. I can only attest to my own experience though.
In my opinion, for the money, you could do much worse than one of these. The feature I enjoyed the most, although it is often viewed as a draw back for traditionalist, is the slim V shaped neck profile of the Gretsch resonators as they feel great "in hand" and make fretting chords and pulling off large stretches like Robert Johnson style turnarounds much easier. One downside to beware of with these guitars is that the tuner buttons have a tendency to crack and break off over time, but replacements are inexpensive and readily available.
