Digital BW, The Print

I will be presenting my first display of 19 images in a few weeks 
here in Austin, Texas. Which brings me to some framing questions. My 
requirements are: low cost, with professional look, ability to take 
images out and replace with new ones, and, initially, no expensive 
hardware, such as pricey dry mounts or pricey mat cutters.

So, here are my questions:

1) looking at the mats at pictureframes.com, are their mats of 
decent quality? I would like to have the mats be thick, and with 
nice 45 degree cuts. The images on the site do not convey enough 
info.

2) I will have non-standard cropping on many of my images, which 
will require custom cuts.

3) any vendors with complete framing kits? Yes, I have seen the 
metal frame kits from pictureframes.com, but I have quality 
questions with their mats. I am willing to pay some more for nice 
mats, because I believe a poor quality mat, with a poor quality cut 
really stands out, and affects the display as a whole.

Sorry for the off-topic. But I suspect there are many in this group 
who are curious, as I am.
