After reading this thread I decide to get two pairs from zenni. Since I was due for a new pair anyway. I went for a $46 Ti frame and a $26 memory Ti frame, ordered last Thursday night and got it this afternoon via DHL, amazing fast turnaround.

So far the prescription is spot on, just like my old pair sans scratches. I went with the default lens because I want to know their quality first, so they are pretty thick.

Default price is amazingly cheap, where they get you however is on options. Thinner lens + extra strong prescription charge + AR coating etc. adds up pretty quick. However it's still half of what local Costco charges.
