Here is a generic full extension that appears to be
a pretty good buy... just found these guys so I can't
speak for the quality....

I plan on buying a box for a shop project...

I am going to be refacing my kitchen cabinets (making new cabinet doors
and drawers). I have been on-line checking out the different types of
drawer slides that are on the market. There is a considerable difference
in price compared to the ball bearing drawer slides and the epoxy coated
drawer slides.
My question is, is there that much of a performance difference in the
ball bearing slides to pay the extra money? Where would be the best
place on line to purchase my hardware?

Any suggestions would be greatly appreciated!

Thanks,
