which PCR machine?

I tried the LightCycler from Idaho.  It worked pretty well, but in my 
opinion its utility will be for those screening many samples for a 
particular product, such as clinical labs screening zillions of 
samples for a disease or a panel of diseases, etc.  This is because the 
machine was designed to let you distinguish between your desired PCR 
product and other junk by doing a melting curve for you.  If you know 
what your product's curve looks like (from past experience, for 
example), then you can see graphically how much of the total PCR 
products consist of your desired product.  Thus, once you have 
experience with a particular PCR product, you can run a zillion 
reactions and theoretically determine whether and how much of your 
product is produced without running it on a gel.  I work in a commercial 
lab where we are always producing different things, so it was not useful 
to us in light of its great expense.  Even if I were in a standard 
university lab, I'm not sure I'd go for it.  I'm a great fan of the 
RapidCycler, made by the same company, and I always like to see the 
actual products on a gel anyway - you get more info that way.
