Homebrew PCBs

There was some discussion recently on another reflector regarding the 
use of a Proxxon KS230 table saw for cutting circuit boards. This saw 
was praised for its usefulness in cutting circuit board material. It 
seems the KS230 is the 230VAC version while the KS115 (120VAC) would be 
more applicable in the US.

I have a tile cutting saw that I bought at Home Depot for (as I recall) 
something under $60 a year or two ago based on recommendations from 
members of this group. I use it with the 0.008in blade (again, as 
recommended on this reflector) and it seems to do an adequate job on 
circuit boards. I don't do a lot of circuit board cutting, just what I 
need for my rather modest hobby activities.

The Proxxon saw costs around $130 from a source I found in the US. It 
seems likely that the Proxxon is a better quality saw in general than 
the tile saw.

Is there anything to gain by upgrading from the tile saw to the Proxxon? 
If so, how and in what areas would the Proxxon provide better 
performance than the table saw for cutting circuit board material?

Thanks.
