Yeah, J&R was the cheapest I saw online, better than Amazon... I actually ordered another one for myself since the "company scope" is elsewhere. It was $59.99 including shipping,. but apparently they're out of stock at the moment (the 400X is out too). Hot commodity!

On the topic of the 400X, it works and is great for getting some super-close trichome pictures, but it's very tough to focus anything at that level and keep the scope steady. In short: good for looking and pictures, not that useful for finding pests...
