I would like to buy some sliding folding doors for a summer house i'm going to build. Has anybody bought some before? Any advice / good companies / rough price range? Thanks

The panels need to be glass and preferably wood framed. Is is cheaper to buy the hardware separate from the panels? Will buying the parts separate possibly cause installation difficulties that could have been avoided if all the parts were instead bought from the same manufacturer (and/or sold in one complete do-it yourself kit)? Is it possible to keep this do-it yourself project under $2000?
