You were actually talking to two separate people, myself and Nick, on Christmas day. Normally our response time through email would be just a few minutes, but it went up to a couple of hours on this particular day because we were with our families.
I don't see that this exchange reflects poorly upon us. Our system is simply set up to use configuration files instead of the command line, as we explained. Apart from Epic's minor bugs, there's really no difference from the renter perspective, as the functionality is exactly the same. LocalMap allow mods and mutators to be specified just as the command line does and we have numerous renters who are doing it.
The fact that we use configuration files and not the command line should really come as no surprise to you, because it is also true of our UT2k4 servers, and you say that you rented some of these.
Our pricing is in line with the quality of our offerings as we explain in many other places on this site. You get what you pay for in this business, as in many others.

I would still be happy to help you resolve whatever problems you may be having with LocalMap. I wrote the FAQ response at
viewtopic.php?f=15&t=3506 and I have successfully applied these methods to every server that I have seen with problems.
