If you haven't tried it, you absolutely will not believe the range, depth and sophistication of the stuff you can routinely get on eBay, often for pennies on the dollar. Need a fume hood so you can do your experiments more safely? I just got a $2,200 model for $150. Slightly used, of course, but what do I care? Need an $800 vacuum pump for your experiments with vacuum vapor deposition? You can get one any day of the week for maybe a tenth of that, on eBay. And yes, if you need some magnesium ribbon to, um, make your Grignard reagents, you can get that too, no questions asked.
