For my part it is a waste of time if you intend to detect your RT-
efficiency by another way than PCR. The interesting cDNA may have
so low concentrations that you are not able to prove its existence
simply by pipetting your post RT sample on a gel.
An alternative might be performing the RT with labeled specific
primers. But talking about saving money I guess you would spend
more in labeling than in performing a PCR.
