I have some 53c825 based cards has 8-bit SCSI bus for both internal and external connectors. For buying new one, definitly, the 875 based card is the better choice. 825 works great if you do not need 40MB Tx rate. I believe this is supported under FreeBSD. I have not got 875 working at 40MB yet. It works as 825 right now. 810 and 815 are older generations. Price is $50 for 810/815 and $90-100 for 825/875. -Jin
