honestly Ive had really good luck with Craigslist, mostly computer stuff and cars (also bought my xbox and pvr from there)
I really like it, just gotta talk with the people for a few days to make sure they arent going to do something wild
aywho from what Ive read and heard the HdPvr specifically doesnt harness much CPU/RAM Power, so it actually works rather good on lower end PCs
I have a Mac though so I cant confirm this... but even on my mac my Pvr seems to run smoother than my Easycap
dont be sketched of CL, its really awesome I think
