Having a changing table is a wonderful option, of course having a changing mat is nice too, that's what my Mommy uses when it's time for me to be changed.
I have to second Tyger here, will you be building the furniture or are you looking for a place with ready made furniture that you can order?
If you want to whip something up, I've heard of many AB's getting a lot of mileage out of standard dressers with a wide surface area, something similar or like the one via this link:

When you have the dresser, you then get a small padded mattress or a changing pad and adhere it to the surface, the drawers become the storage area for your diapers and other changing supplies. I think this is the method I'll likely try out when I have a place that's a bit larger.
I also had an AB friend who owned a treatment table, like what you find in a doctor's office and he used that as his changing table:

Finding an adult changing mat for purchase is simple enough, just search eBay and you'll find some. Adult Changing tables that are made and ready for purchase are quite hard to come by. I know Baby Apparels make a ton of Adult Baby furniture, I don't know how reliable they are with regards to shipping or how good the product is, but buying from them is no more or less expensive than trying to customize a dresser or buying a patient table. So, if price isn't a concern, this might be the cheapest and easiest route to go:

Of course, you could just settle for a nice Adult changing mat too, I still feel babyish when being changed on one, they're a lot cheaper and they take up less nursery space.
In any event, I hope you enjoy your new place and I hope that you are able to find or produce what you are looking for
