Just looking for one to play around with. I have a cheap one I got off eBay. I mostly use it at night for star gazing and such. I'm not ready to invest more than $50 in it yet. Want one that can be very easily seen. Don't really care about color. I'm very new to this, it's something that had just peeked my interest. I would like to get into building my own one day.
It sounds like a 532nm green might be what you're looking for. I highly recommend the GearBest XY-016. 532nm is in a visual sweet-spot near the highest visibility.
