Alrighty, here's some non-trance tracks then:

Electro:
Anything by Vitalic, especially his 'Poney EP' release, which contains the tracks Poney Part 1, Poney Part 2 (aka You Prefer Cocaine (Felix Da Housecat Rmx)), La Rock 01 and You Prefer Cocaine
Anything by Legowelt, I literally like every tune of his, but to mention a few: Disco Rout, Gotoburg Jacks, Dirty Tango and Pandamonium
FPU - Crockett's Theme (remake of Jan Hammer - Crockett's Theme)
Michel De Hey vs Secret Cinema - Another Sweater (Sterac Electronics Rmx)
Alan Braxe & Fred Falke - Rubicon
Tiga & Zyntherius - Sunglasses at Night (Tom Middleton Cosmos Re-edit)
Bolz Bolz - Take A Walk (Dima Neo-Romantic Rmx)
Bryan Zentz - D-Clash
Two Lone Swordsmen - Neuflex
Adam Beyer - Ignition Key (Speedy J Rmx)
I could probably mention loads of other tunes, but I better stop now.
The techno tunes ranges from traditional techno to hard and minimalistic (aka schranz) to the more housy kind of techno. I don't know if they match your definition of 'techno' and if you're able to fit them into a trance mix, but I do reckon the Benozal remix will fit in nicely. Some of the electro tunes, especially Vitalic, could probably also easily fit into a trance mix as they have lots of synths as well.
