Single-mode cards are very expensive (the optics), for short distances (several hundred meters) use multimode, the fiber is also much cheaper then. And yes, you don't need any switches - I use them exactly this way. As for the price... Frankly, I don't remember, the company paid for this :-), I vaguely remember something like $700 per multimode 155Mbps card. And the difference in pricing between single- and multi-mode card was something like 3:1.
