Sam , you should save this to copy and paste every time this comes up.
I totally agree with Sam ,maybe will be better try to find a good second hand scope in good condictions before buy a cheap new one i have try the AmScopes and do the job but for example i have bought a bausch & lomb sz4 in ebay for 150$ and a leica sz6 for 200$ and compared with a new amscope the quality is much more better
