I'll leave you with these two thoughts (and they're worth exactly what you are paying for them):
I can make an acceptable recording with budget mic's and preamps if I have to. On the other hand, if the recording doesn't happen, it does not matter how good the mic's were.
If you are charging someone for your services, you are presenting yourself as a professional. If that is the case, what is your professional reputation worth? Do you want to have to apologise to the client because your laptop took a dump in the middle of the concert?
Maybe that's perfectly acceptable in some circles. You know your target clientele so YMMV.
you do make great points and i will most definitely get a back-up in the hopefully near future. the reason for me buying new/better mics then what i already have is not only that but i also need more. right now I don't have enough mics to record a full band. i do have mics to do a drum set and a singer but i know more will be needed in a live gig. i wish i had the funds to get mics and a backup source but unfortunately i do not.
