Alex, I have a GT-2500 here on my desk. It's a pretty solid office machine working reliably with the iscan and the xsane frontend. However, speed is slow with the default settings so one has to make sure that the speed button is activated. Some features like the ADF-duplex scanning aren't working with the graphical frontends but just from the commandline (scanadf).
As to the scanning speed: 27 PPM seems to me to be the usual advertisement ballyhoo, anyway the GT-2500 makes in b/w scanning with 300 dpi a page in roughly 4 seconds giving 15 PPM. However the GT-2500 comes with an ADF-unit, and if you don't need it you would have to pay for something useless. Although the GT-2500 is quite inexpensive compared to other machines of its class and quality its price is clearly beyond the normal customer's budget (and the ADF-unit makes pretty a portion of it). So you may look for a pure flatbed scanner, Epson scanners are in any case a good choice if speed is the criterion.
