Sorry to hear that. Actually I just purchased 2 of the sonnet cards last night from buy.com for $39.00 (here):
http://www.buy.com/prod/sonnet-presto-g ... 94752.html
Funny, it's gone up to $42.24. It's amazing that online companies like buy.com bump up their pricing as soon as an item sells. They think that theirs some kind of demand for them now when their isn't. But again, that's typical of online companies like this. At least their is a 45 day return policy (15 days better than OWC and newegg.com).
I was initially going to purchase it from Other World Computing (here):

but even as a reseller I was not able to get it at a lower price than the $49.00 that it was selling for, as their was no discount for it on their site.
Anyway, I purchased those 2 Sonnet cards (as a future backup) because my Syba (SD-PEX24009) Card (here):

stopped working when I upgraded my OS, so I turned to my Rosewill card (here):
http://www.newegg.com/Product/Product.a ... 6833166015
and it worked just fine. I'm glad that I listened to Going Bald and got that card as it's no longer available... I got those 2 Sonnet cards as I was told (by someone who has the very EVGA SR-2 setup that I have) and they supposed to work with pretty much any system setup. Well, if I run into the same issue that you did, at least I'll be able to return them if they don't work...
