I think an A-105 is a great choice. It's basically a C3 cabinet with internal speakers.
I pray you get a Hammond. I finally have my first Hammond after a few years of waiting and praying for one. It's a model CV, which is essentially a very early version of what became the C3. I love it. Has a real nice tone and bass response in phenomenal. As mentioned already in this thread, the CV doesn't have split vibrato/chorus (all on or all off), ratcheted drawbars, and no percussion. Drawbars can be converted for about $300 and TrekII percussion can be added.
I think your best bet is to find a Hammond locally. Ebay is nice and that's how I found my CV, however, shipping rates are killer if you can't pick it up yourself. I spent around $500 just on shipping and it's probably going to be more than that now with the rising fuel costs this summer.
