Hello everyone I'm new to the forums and wanted to say thanks. Ive been wanting to purchase some high power lasers for a while but with the cost of tuition Ive been holding off. I didn't know which companies were selling quality and which were full of hot air. After reading some of the post from the vets here I decided to go with Sanwu! They look great and for what you get for the price It was hard not to go with Podo's equipment. I ended up getting a few Spiker and Spiker Saber models in 1W 405nm, 4W 465nm, 1W 520nm, 1W 639nm, and a 100mW 532nm pointer. I placed two orders today so I post when they arrive. I'm so excited and cant wait to try new lasers in the future. I have a question for any of the vets reading this post. I really want to find a high power yellow laser and so far for the price and quality I keep leaning towards Dragon lasers. Does anyone have anymore insight as to what other brands or models I should look into for this wave length? Thanks again, and I hope I'm post this in the correct place.
