For going through a large number of time series photometry CCD frames MUNIDOS is my favourite, in fact I think it is excellent. However for working on a lot of different fields in a night I use DAOPHOT II within ESO MIDAS, which has a nice internal tables system. Unfortunately both MIDAS and the NOAO's IRAF run on UNIX or VMS, but not DOS. I am aware that there are commercial DOS and Win NT packages for CCD work (ie MIRA), but I have too small a budget to pay for these packages, so have had to learn to get around inside a UNIX computer, which isn't so bad.. MIDAS and IRAF are available for free (MIDAS) or a nominal cost (IRAF), which is certainly a lot less than some of the commercial packages advertised to the amateur market. Dewa mata Paul Warhurst
