For the most part, with SCSI controllers, you get what you pay for.
The other widely used alternative, the BusLogic BT94x and BT95x
controllers, are in the same price range.
On the other hand, that high price gets you a very high performance
bus-master controller.

This seems to be the one exception to the above rule. The NCR 53c8xx
controllers are good performance for a very good price.

The only one that would be considered "in the same leage" would be the
NCR controllers mentioned above. There is one other that people
mention, "Advsys", or something like that, that is in a similar price
range to the Adaptec and BusLogic, that is supposed to be "Adaptec
compatible". All other "cheaper" controllers are going to be in a
whole lower class (if they work at all).
FWIW, don't even bother with ISA controllers if you're at all
interested in decent performance.
