After about a week of learning from Chinese K40 Laser Group, YouTube, and talking to friends with lasers, I could not stand it anymore and bought a K40 from ebay..
Looking back at sold history on the listings, I saw prices as low as $340, but the going rate at this time appears to be $385. I found a listing for $375 and clicked make an offer and offered $350. He counter offer $370, which I took because I really want one.
I specifically ordered one from USA. They say it should be delivered in a week!
I can't wait!
UPDATE 1
Shipping label created same night I ordered. Two days later it is in transit!
UPDATE 2
OMG It's going to be here today!
UPDATE 3
It's HERE!
Cat for size comparison...
I wonder how much it cost them to send something this big and heavy via UPS.
