Sounds good,  But why don't you try to make the board more compact?  7X10 is
pretty big considering my SSTC boards were 2X3...  And the H bridge being on
there doesn't account for the large size,  I managed to fit an entire SSTC
into a
  5 X 6.75" base,  see here,
www.hot-streamer-dot-com/electrontube/temp/dsc01325.jpg and
www.hot-streamer-dot-com/electrontube/temp/dsc01324.jpg

It might seem that some people would want to make their own H bridge or
Halfbridge that way they could build the coil to their caterings.  45$ seems
like a lot,  considering those large SOT-227 IGBTs will cost about 20-30$
each depending on where you get them...

Good Luck.
