I've been using the photoetch method for a little while now, I've a small write up with photos at http://cyclerecorder.org/blog/20070609 . The results with FeCl3 seem very good to me, though I've never tried the toner transfer method. The boards I've used are pre-sensitised but I must try using applying photoresist myself, and try a test pattern/board to see how fine I can get the traces..
