yeah, I bought a couple of fakes, don't work, and really look different from the original part. This one though, is very good: http://www.ebay.com/itm/Nokia-N900-T...item5ae3131ac7

It comes with the outer rim, frame and IIRC the speaker, so that you don't have to do difficult disassembling. The original frame is so well glued to the digitizer that is really hard to take it out without inadvertently distorting it.

The plastic is also polarized like the original, and unlike most cheap replacements. Weirdly it came with black tape over nokia logo. Go figure.
