there is PLENTY interest here for this, 10 units will easily be met, most likely 20+, so expect a decent discount here, I will have details soon(following completion of shipping the DVDO Edge scalers, which is mid this week), thanks for all the hands thrown up so I can get a good estimate

Roger, you won't need the SPDIF mod with the HD621 you have, if you want the best quality digital signals via HDMI then the digital transport ed. will do the trick nicely, it has a updated power supply with toroidal isolation transformer, a updated high-end clock with dedicated power supply itself and disabling of the analog audio outputs, all this adds up to the highest quality possible digital signals via HDMI(video and PCM audio) and the 4x SPDIF mod for those that want it

thanks
