Trimble can try and connect you with a dealer.   It seems to be
hit-or-miss.  Diamond Point (DPIE online) has the E for £896.00 Exc
VAT.  They also have one last Mini-T for a bit less.

It's a bit pricey.

DPIE has the starter kit for £1,139.00.

If you want to go retail there are the Fury or FireFly II and Jackson
Labs (JL) will just sell you one.  If you're willing to buy used the
(much) older Thunderbolt (no E) can be had on Ebay for various prices
< $500 mostly from CN or HK.  James Miller (G3RUH) is still selling a
GPSDO for £260.  JL also sells a TCXO eval. kit but it's a bit
twitchy.

If you poke around you can probably get ADEV numbers for most of these.

Naturally if price is of no or little consequence you have a plethora
of choices.
