The 4/110 doesn't even have "normal" esp controller, it's a weird mutant
thing.

4/300.  Faster (25MHz), fairly easy to expand (has 8 SIMM slots on board
that can take 1MB or 4MB and you can find 48 SIMM expansion cards).

The 4/400 is faster still but has no onboard SCSI.

The 4/300 has a P4 connector for a framebuffer.  P4 cg6 cards should be
nearly free nowadays.

Of course, you could always go for broke and try to find a 4/600 board.
