Buying memory. Advice needed

Hello,

I would like to upgrade the memory of my Apple Laserwriter 8500 which was made in 1998. I have found many places to buy memory upgrades for this printer but I thought I would first ask this list for some recommendations on reliable memory suppliers and maybe some tips to avoid purchasing faulty or poor quality memory. I am looking for a 32 MB SIMM and I see many on ebay but often the sellers do not know the technical specs and only know that the SIMM was pulled from an older system. Should I just take my chances and consider buying a SIMM on ebay hoping it will work or could someone recommend a good memory supplier for me?

I read on a website to avoid buying "remanufactured" or "re-engineered" memory. How can one really tell if a SIMM has been "remanufactured" or "re-engineered"?

If the memory was just pulled from an older Laserwriter 8500 should I just buttume that it should be the correct specs and should work reliably?

The specs are: 32 MB RAM SIMM 70ns or less must have a 2 KB row (11 bit x 11 bit) refresh rate 72-pin

For example, here is one of the ebay listings:

Thanks for any advice,

Mike
