Dev. board options

I've got a coding project in the works targetting m68k/Coldfire and I'd like the option to run on real hardware rather than just in a simulator, but I'm having a devil of a time tracking down anything that would be suitable for my purposes. As far as I can see, it seems like the only such products that are still generally available on electronics supply sites like Digikey and Newark are in the neighborhood of $100-200 for something that includes less than a megabyte of flash memory and 8-32KB of RAM, and more often than not is just a bare board designed for Freescale's "tower" system. (Considering they used to make Coldfire development kits that would run an embedded Linux, that's a pretty appalling state of affairs.) I've seen specs for older boards like the MCF5208 or MCF5485 that look more like what I'd want, but they seem to be pretty much completely unavailable.

 

What I'm looking for is a development board or other standalone SBC that has one or two serial ports, at least 128KB of RAM, and ideally a megabyte or two of flash storage. (I'm not looking to use a vintage 68k computer system like a Mac or Amiga, since using those involves not just using the processor, but learning my way around all the quirks of the system hardware and circumventing the normal boot process.) I'd be happy with more, but that's what I'd consider necessary for my goals. I'm open to building something myself, if the parts and board are fairly easy to procure. Is there anything like that out there currently, or readily available second-hand?
