MJ-Research DNA Engine

[Soonmyoung Paik]

Dear Netters, 
Sometime ago, I read a negative posting in this group about  MJ-Research 
DNA Engine (PTC200) - a fluctuation of annealing temperature. I was 
going to order that equipment for the lab, mainly because of its 
flexibility of exchangeable blocks. I called the MJ Research to enquire 
about the possible technical problems, and got negative response. If 
anyone had similar bad experience with DNA Engine, please e-mail me or 
post follow up. Thanks in advance.
