PCB Etching and Sealing

[Neo Tribal]

I'm considering etching my own PCB's...

What products/methods would you recommend for this?

Ferric Chloride or Photoresist?

And for sealing, what sort of substance is best for coating the traces 
(or is this not even necessary?)

Has anyone ever used those Laser Printer Toner Transfer things? Are 
those worth the trouble, or is freehand the best way to go?

  thanks for your help
