Plenty decent to do any SMD stuff which you can possibly use without THP.  
8/8 rules work just fine. There is no significant difference to  
photoprocess in my experience, if both done at home. Of course you can get  
a bit better with photoplotters and stuff, but that's not generally  
homebrew any more. Also, you soon run into underetching problems with both  
processes anyway.

No. It makes no difference at all, some even had worse results.

The quality of TT can easily be what one would call "flawless", but the  
board will still look homebrew. Because of THP and soldermask. Milling is  
worse though, in terms of looks.
