A Good Place To Buy Good Drawer Slides?

[shilala]

I need a couple dozen sets of full extension 100# drawer slides, 22" or 24", I'm not exactly sure what size yet. I want ones that have matching face frame brackets available, both front and rear, so I don't have to build out the sides to mount them. Not plastic ones, good, strong metal ones.
I've been using Knape & Vogt KV 8400 series and I'm very happy with them, but they seem pretty expensive, comparatively.
These will be going in desks, short file cabinets, and other furniture I'm making for our own office, so I sure don't mind spending a little extra.
It's just that I figure you guys have far more experience buying cabinet hardware than I do, and know where to get the best bang for your buck. You might even know of a line of glides that are just as good, nearly identical, and half the price. I figured it'd be a good idea to ask.
Any suggestions would be very much appreciated!!! :)

Try hardware resources . They have them reasonable

I've been happy with diamond brand about half of what the kv cost and hard to tell the difference between them imho.

100# 22" with front and rear clips cost about 9.00

There are three Richilieu distribution centers in Ohio. They are one of the largest cabinet hardware jobbers in North America. Typically their local center will carry "A" label such as Accuride and/or KV and also off brand for much less. There are now a ton of different "brands" but, like a lot of the import tools with different company labels on them, many are made in the same plants. In general, the quality of them has improved over the last few years. Used to have "falling ball bearings" on a regular basis.
See if someone in your area carries US Futoba. They are a decent quality knockoff.
