I don't think I'd buy from either of these sellers..but can you tell me what you think about these two microscopes? Good/Bad - waste of money - the screen size 640x480 or whatever it is confuses me..is that normal? (since my computer resolution is higher I was wondering if that was low or okay or whatever since my daughter's games are at that resolution).....This is for science/biology, be cool if we could get into cell structures and stuff..anyhow..are these magnifications decent or are they just like the play ones? Any advice appreciated..still learning..
