Any thoughts on the Epson SpectroProofer? Is it as acurate as the i1 spectrophotometer?
There's nothing to do with the SpectroProofer that limits it for fine art use. In my experience it delivers better measurements than an i1 Pro, and a hell of a lot easier. You will of course need profiling software but if you're serious enough to be looking at the SpectroProofer you've probably moved beyond consumer level packages for this. You can also use it for calibrating (what Epson calls linearizing) your printer if you have the corresponding Epson branded media.
A few downsides, it only works with roll media and the maximum drying time has been reduced in the current version of the software. It's also tied to the same model printer as has been pointed out. If it's available bundled for not too much extra (like mine was) it's worthwhile looking at. You'll probably need an i1 Pro (or similar) for spot measurements though as well.
