I purchased an AmScope "40X-1600X Trinocular Biological Compound" microscope (model T490A) through Ebay and I've had a few weeks to "break it in". Here's my short review, for what it's worth to anyone considering a simular purchase.
First, my purchase price was under $300. Overall, I would rate the unit as mid-grade, but a very good value for the price. (Keep in mind that having used some very high quality lab microscopes in the past, my saying that this unit is mid-grade is not a bad thing; it should be more than adequate for home/hobby or basic lab work.) I consider this unit an excellent choice for anyone looking for a quality, full feature microscope who does not wish to spend $1000 or more for a more "professional" unit.
The controls are tight (i.e. no slop or play) and seem to be well constructed. The optics are sharp and clear. The lighting controls are very good, although the lens assembly for the halogen light on my unit has a couple of black specks inside the sealed assembly. (It doesn't affect the performance.)
At this point in time, I do not have any negative remarks to report on this microscope. I am very pleased with my purchase and feel safe in recommending this brand to others for their consideration. I'll be sure to post an update in this forum if anything changes.
