I have the suite from the romanian guy, and its amazing, I had some trouble installing it originally, but i emailed him, set up a time, and he remotely configured my laptop, (while i was sitting in my X) and walked me through the whole thing. I would recommend plugging a battery charger into the X, because when youre sitting around for a couple hours tinkering with settings and scans, it draws down the battery quite quickly, or maybe i just have a weak battery in mine. either way, i connected a charger, and plugged in my laptop as well, and it is easy to use. the TIS is nice as well.
