Re: parallel port signal to relay / source ?

I checked Jameco, they offer a SSR for 8 bux , 2 amp/230 VAC prices
go up from there.

I guess now I have to look at if a photodarlington, mechanical relay
is better/slicker/easier than an SSR.

seems that if one puts together a board, you get the option of
putting in those neat LED's and all those goddies.
