I dont like the look of wire wrapping ... it doesnt look to reliable to me
but then again, there are many companies that use it .... I wont though!

Etching is a pain if done with transfers onto copper board etc.... using
the UV senstitve boards is a big improvement, just draw with a nice black
pen on the board and stick it in the sun!

My favourite, for one shot stuff is to use Veroboard (Probably a trademark)
which is like perfboard but with copper tracks running down the back. There
are variants on this, such as holes grouped in threes or fives, but I find
it very easy to use, and more reliable than perfboard, where you have to
interwire the components on the back (yuk!)
