I've never heard "level one" used in this context. the closest would be
"layer 2", which refers to mac-based switching, and might be what you mean.

3com is not an exceptional switch vendor, except in the historic sense.
they make OK stuff, but I don't think I'd give them special credit against
any of the well-known brands (dlink, netgear for commodity, hp-procurve,
cisco and some others for higher-end, enterpriseish stuff.)

a dime-store, no-name 8-port gigabit switch would serve just fine.
at gigabit latencies (with a normal stack, etc: ~50 us), internal details
of the switch are basically irrelevant. small switches like this are
probably single-chip, giving appliance-like in reliability, insensitivity
to the name on the case, and probably line speed.
