Removable Tray Recommendations?

I have been using some inexpensive IDE trays but recently they have been dropping like flies and when they start to go they get unbearably loud and cause all sorts of intermittant disk problems.

What recommendations does anybody have for relatively quiet and solid performing PATA removeable trays. In fact, not just PATA enclosures since I'm beginning to replace my PATA drives with SATA...
