Help tracking down z97/z87 itx motherboards in Europe (uk)

So I'm building a new pc as a student on quite a strict budget, however I've managed to acquire a 4690k for £75.

My build needs to be a mini itx since I need to take it to and from uni on public transport, but I'm having a lot of trouble finding boards.

My budget for the board is around £100 but the only one I can find is the ASRock Z97M-ITX/ac which from what I've read is not a fantastic board and is not a particularly stable overclocker. I'm not opposed to buying used, but if anyone could help me out finding any other z97/87 boards that I can order to the UK I would be extremely grateful.

You arent going to find a good overclocking board for that price.
Any Z97 board for around 100 isnt going to be great.
I have the same board and I have my 4690k at 4.6ghz with like 1.25v. And its still is always around 55C which is nice.
You really dont need a great overclocking board with devil cannons since ram overclocks arent great even on good boards and its not the board so much as the CPU itself that dictates the overclock.

After days of of searching I found a asus z97i-plus this evening for £80! Popped up on Amazon warehouse. Nonetheless thanks for the answer.
