Any PCI FPGA cards?

Hello. Curious if there are any PCI FPGA cards out there that would be well suited for bitcoin mining.It doesn't need to be the fastest or anything, if i can get 30 mhash out of it i would be happy. It Doesn't need to be anything fancy, just something to get started with. It Would be used under linux. Ive got a machine with 15 open pci-extended slots that runs almost 24/7 as is, figured i could get some mining in. I was debating going the usb asic route, but if i loose interest im stuck with something that can only be used for bitcoin mining, with a fpga i could reprogram it to do something else.Also the large machine i am planning to use does not have any usb ports, and i really dont want to set up yet another machine around here, so a nice pci fpga card would probally be best so I can use the hardware ive already got running. I wasn't able to find anything, hopefully there is something out there.
Any help is appreciated.
