I have to agree that positive photo method if far easier and better 
than TT.  I read on here what some seem to go thru to do the TT 
method to get good results.  I find the positive photo method much 
much easier.  I guess if you don't do this much TT might be a way to 
go but if you do boards very often and have a place you can setup a 
exposure frame and a etching tank you can produce boards very easily 
with better results.  For most it seems that TT method is hit and 
miss on getting a good board as can be seen in the photo of that one 
post.  I know that there or some on here that seem to really have 
the TT method down and have good results, but I have a idea that it 
took them a while to get to that point too.
