I might suggest that anyone could do a review of the Fantasy figures currently available and post it on the internet as "Fantasy Plastic Soldier Review"... there's not that many sets and only a few company's producing them if you stick to 1/72 ... why try and force someone who's not that interested to do it, doubtless PSR is run by hobbyist's like the rest of us after all..
I'm joining this late as I am just getting back in town, but I know from experience that PSR not only accepts feedback via the provided contacts, but will amend their reviews if you have info of which they were previously unaware. In my experience PSR has been thankful for the insights and very gracious. I might not always agree with PSR's opinions, as a friend of mine is fond of quoting, if two people are in 100% agreement all the time, one isn't thinking for himself. As others have said numerous times, PSR's contribution to the hobby is immeasurable.
My own theory on the nature of the site is it is a one-man operation. I get the impression he started out reviewing figures he bought but as his site grew in popularity smart manufacturers will send him examples of their output. If they don't they should IMHO - after all, even a bad review still gets their output publicized. And if you aren't confident of the quality of your product maybe you should look for another line of business?
