Totally random suggestions not taking price/SQ into account at all, from someone who doesn't wear glasses (I'm imagining with my sunglasses):
Koss ESP/950
Kenwood KH-K1000 (this isn't the same as the K1000 mentioned previously in this thread, at least I'm assuming - there are two different headphones called K1000, the Kenwood (which is still made), and the AKG (which is no longer made))
Audio-Technica ATH-ESW9 (this one's a maybe)
IEMs (various)
I wear my Denon C751s with sunglasses almost all the time, and don't have an issue. I don't wrap the cables around my ears though. Same for my Etyplugs (which are similar to the Etymotic in-ear headphones, they're just hearing protectors instead).
The Koss (apart from being one of the better headphones ever made) have almost no clamp pressure, and huge ear-cups, so I imagine them being very glasses-friendly. The Kenwoods are in a similar boat, they're closed-back and dynamic too, so they're probably more accessible for what you want (oh yeah and they cost less).
The ESW9s are a maybe - they're very light on-ear headphones with decent padding, they may or may not conflict with your glasses though. I'm not really sure. They'll get the closet to the Grados of the three, mostly owing to their on-ear fit, and they look super cool (for whatever that's worth).
I'm not sure how more conventional "comfy" models like the K701 or HD 600 or Bose AE2 (hey, knock the sound all you want, but they're comfy headphones) would fare with glasses though - I just see the earpads putting too much clamp on the glasses and causing discomfort. I can't think of anything else that's got that "super mushy" quality like the Koss or Kenwood. Supposedly Beyers with the gel pads get along with glasses, but I've never tried gel pads; it will change the sound of whatever headphone you stick them on (and they look kind of dorky).
