I did bridging for awhile with an old 486DX66 with three 3Com 509s and it worked fine.
The price was just the three boards. There is always an old PC around somewheres...

Another problem with commercial products is that they do not support protocol filtering.
Linux 2.1.2X supports selectively switching off and on protocols to be bridged. That is a very
