I see two problems with this list:

first, except for a few known makers (Sandisk, Transcend, Toshiba), the brand which is printed on the card says nothing about what card it is. "Cardsforcheap" (fictional name) just prints the "Cardsforcheap" brand on whatever low priced excess inventory they got that particular week. Next week, you'll get a completely different card under the exact same reference.

second, one of the big problems with microSD are the contacts. You'd be surprised how many malfunctioning cards can be resurrected with a Q-tips and alcohol or contact spray. The cards are not designed to be taken in and out regularly, but to be put in a phone and left there (so that you can choose how much memory you need). The contacts in your N900 can also be cleaned by inserting a card slightly wet with contact spray in and out a few times.
