I did photo-etch some boards back in the day, but I can't recommend it. The chemistry isn't horrible, but it's somewhat toxic and messy.
That's how boards are made for real, so it must be possible to get good results; certainly better than milled or toner-transferred boards. But there's too many cheap suppliers to justify the time and effort.
A representative list would be
http://www.myropcb.com/
http://www.olimex.com/
http://www.custompcb.com/
Any of these can turn around a two-layer board, with silkscreen, solder mask, and plated through holes, in something around a week. The cost is something under a hundred dollars.
