Query: Fragile, worth the price only if you absolutely need exactly this layout and features

I knocked off two key caps (collision with keyboard tray mounting rails) and couldn't just pop them back on, because their delicate suspension pieces were broken. I bought this for the control key layout, but that benefit was outweighed by absent Windows key. The typing feel and touchpad accuracy were okay but nothing special. For half the price, I find the Solidtek KB-540 perfectly adequate and not fragile. The USB versions of both are plug-and-play under XP for the basic touchpad functions, I didn't try more advanced functions.
