Reverse transcriptase for RT-PCR

[RICHARD P. PHIPPS]

Hello, net

     I'm just about to do a big, expensive semi-quantitative RT-PCR
 experiment with mouse lung tissue and I want to squeeze as much info
 as possible out of it.  I've got quite a bit of experience with
 RT-PCR using USB MMLV-RT, and I was wondering if anyone is using
 RNAse H(-) RTs such as superscript from BRL.  
 Is it worth the extra expense for this type of assay?

     Also, I'm planning to use total RNA prepared by TRI-REAGENT and 
priming RT with oligo dT.  This is what I've always done successfully,
but if anyone has a problem with it, I'd like to know.
 
Thanks,
