Just seen a post over on T-Shirt forums, and found out that Epson actually have their own CISS systems built into some of their printer models that are marketed in Asia regions...
They are named L100/L110/L200/L300/L800
Quick Google and found that this seems to be true:

Or on futher reading, it seems that these are new models, so UK availability may be in the pipeline. This on the heels of Epson bringing out a dedicated sublimation printer.
