I second that.
You'll have to wind your own for this type of application.  Off the
shelf gate transformers will generally not cut it.

Skip,

While i havent had direct experience with buying GDTs, i have heard of
others who have bought GDTs and their performance was rather
insufficient for SSTC work.  They had too much leakage inductance mainly
because the cores were small, requiring many many turns of wire.Also
they did not interleave the wiring, but rather 2 seperate windings were
wound on the E-I core.

Winding a GDT on a toroid, with a twisted group of wires is very easy to
do, and the results are usually very good.  You can even make your own
customized shielded wire packs for even higher coupling between
windings.
