I have no experience with topre personally. I had considered buying one of these to try, but I looked through sales threads here and elsewhere to see how much luck people had with reselling, and it seemed in most cases they either lost money or they didn't sell very quick. Had I had the money to loose I would've done it but it's been an expensive keyboard month and I have my sights set on a g80-18xx
Good to know about the uniform 55g being the most popular. I had considered grabbing a novatouch tkl from a store that has 30 day returns on keyboards just to see if topre was something i might enjoy, but the more i read about it it seems the consensus is its not quite the same experience as a uniform realforce or hhkb.
